Machine learning defined more precisely

Machine learning is an area of artificial intelligence that enables computers to learn from data and continuously improve themselves instead of being explicitly programmed. Algorithms are trained to recognize patterns and correlations in large data sets and to make the best decisions and predictions based on these analyses. This leads to automated knowledge generation, the identification of correlations and the application of these findings to unknown data sets for the optimization of processes and the prediction of future developments.

How does machine learning work?

To make machine learning effective, training by a human is required. There are various learning models that use different algorithmic techniques. A model is selected depending on the desired result and type of data, whereby a distinction is made between supervised, unsupervised, partially supervised or reinforcement learning. Within these models, specific algorithmic techniques can be applied according to the intended result. The algorithms are used individually or in combination to ensure accuracy in the processing of complex and unpredictable data. This development process is iterative and is often repeated several times until the desired quality level is achieved. Once the learning process is complete, the trained model evaluates unknown data in order to make improved decisions. The main goal is for the computer to learn autonomously and adapt its actions without human intervention.

Types of machine learning algorithms

Supervised learning uses known data, recognizes patterns and learns from a training data set. It aims to accurately predict a target variable, such as when forecasting electricity consumption or assessing the risk of investments.

Unsupervised learning visualizes large amounts of data, performs cluster analyses and independently detects hidden patterns or groups. It is not suitable for precise predictions, but requires an assessment based on more flexible factors, suitable for the desired business application.

Semi-supervised learning combines supervised and unsupervised learning, uses sample data with target variables and unknown data. It is used in areas such as image or object recognition, where a small amount of data with target variables and a larger amount of data without target variables are used.

Reinforcement learning interacts with the environment and learns a strategy for solving a problem through a cost function or reward system. In contrast to other methods, it does not require sample data, but develops an optimal action strategy in simulation steps.

Areas of application for machine learning

The areas of application of machine learning can be assigned to the individual learning methods. Unsupervised learning is therefore ideal for dimension reduction (recognizing structures, compressing information, big data visualization, etc.) and cluster analysis in the form of market and customer segmentation or recommendation systems. Supervised learning is used for classifications such as text and object recognition or forecasts (demand, weather, sales, customer values, etc.). Reinforcement learning is ideal for autonomous driving, game AI, traffic control, robotics and also for personalization and advertising.

Machine learning and spo-comm Mini-PCs

Of course, our spo-comm product portfolio also includes mini PCs that are suitable for machine learning. We are talking about our mini PCs that are equipped with a dedicated graphics card. The KUMO VI and the QUADRO P1000 are therefore suitable for machine learning, as is our new addition, the NOVA R680E. Even our new 19โ€ณ rack PC, the NINETEEN Q670E, can be used in machine learning, provided it is equipped with a suitable graphics card.

Integrated graphics cards (IGP)

A graphics processor โ€“ GPU for short (for โ€œgraphics processing unitโ€) โ€“ is referred to as integrated if it is installed in the chipset of the motherboard or in a separate die in the same chip housing. The former is referred to as an onboard graphics card.

As an integrated graphics card does not have its own memory, it uses the PCโ€™sRAM, just like all other programs. The size of this so-called shared memory can either be set via the BIOS or is regulated dynamically by the system itself.

All our Mini PCs with an Intel CPU are equipped with the integrated Intel GMA graphics cards or the successor Intel HD Graphics or UHD Graphics.

Advantages and disadvantages of an IGP

As an integrated GPU does not have its own video memory, it only takes up a small amount of space inside a PC. Combined with its low power consumption, it is perfect for use in small devices such as notebooks or tablets. The price of systems with an integrated GPU is also lower, as there is no need for a separate cooling system. Such a graphics card is suitable for all common office applications, but also for industrial use scenarios. Due to the slower clock rate and because it shares the RAM with other applications, an IGP has a significantly lower performance than a dedicated graphics card.

Dedicated graphics cards

In contrast to an onboard graphics card, a dedicated graphics card has its own video memory, or VRAM for short. Such a GPU is connected to the mainboard via a PCI, PCIe or AGP slot.

Our product portfolio also includes systems that are equipped with a dedicated graphics card:

  • The KUMO IV with an Nvidiaยฎ GeForce RTX 3060 graphics card with 6GB DDR6 VRAM.
  • The QUADRO P1000 is equipped with the eponymous Nvidiaยฎ Quadro P1000 and the RUGGED T1000 with the eponymous Nvidiaยฎ Quadro T1000.
  • The NOVA R680E and the NINETEEN Q670E can optionally be equipped with three different Nvidiaยฎ graphics cards: RTX A2000 (12GB DDR6), RTX 2000 (16GB DDR6), RTX 4000 (20GB DDR6).

Advantages and disadvantages of a dedicated graphics card

Since a dedicated graphics card has its own video memory, the RAM is relieved and can be used for other tasks. Another advantage is that the peripheral devices are clocked much faster and are therefore also more powerful. A dedicated graphics card is indispensable, especially for use in workstations or in the demanding DS area, where several monitors are controlled simultaneously or programs such as Adobe Photoshop or CAD for 3D modeling are used. However, the enormous performance is also accompanied by very high power consumption and the development of heat. Therefore, a separate fan requires much more space than an integrated graphics card.

Last but not least, it can be said that a dedicated graphics card is not absolutely necessary for standard applications as mentioned above. However, they are extremely relevant for demanding applications or multi-monitor solutions in digital signage.

General Purpose Input/Output?

The abbreviation GPIO stands for โ€œGeneral Purpose Input/Outputโ€ and describes a universal interface that can be found on many computers and microcontrollers, including Raspberry Pi, industrial PCs and embedded boards. The pins can be configured as inputs or outputs to receive or output digital signals. Unlike specific interfaces such as USB or HDMI, GPIOs are very flexible and are suitable for a wide range of applications โ€“ from measuring a sensor signal to controlling a motor. The pins are particularly relevant in embedded technology, as they create an interface to the outside world and allow the computer to interact with its environment.

More detailed information about the interface here!

GPIO vs. DIO: The differences

While GPIO focuses on the general flexibility in the configuration of pins as inputs or outputs, DIO, or โ€œDigital Input/Outputโ€, refers to digital signals that are processed as binary values (high/low). DIO pins are therefore mainly specialized in detecting or switching digital states. In comparison, GPIO usually also includes analog signals and allows finer control over voltage levels and adaptation to different requirements in some applications.

The pins can have different states: either โ€œHighโ€ (1) or โ€œLowโ€ (0). These states correspond to electrical signals that can be controlled by a software interface. The advantage is that the pins can be programmed to act as either an input or an output. This process is explained here for beginners.

The inputs receive signals, for example from a button or a sensor. Outputs, on the other hand, control external components such as LEDs or relays. This flexibility is particularly valuable for embedded and industrial PCs, as they can be programmed for a wide range of applications.

Possible applications for industrial and embedded PCs

The possible applications in industrial and embedded systems are diverse and include areas such as

  • Automation:
    The interface can be used to control and monitor robot arms or conveyor belts. This allows industrial processes to be automated efficiently and safely.
  • Smart Home and IoT:
    They allow you to control and monitor smart home devices such as light switches, thermostats and surveillance cameras.
  • Sensor technology:
    Embedded systems that work with sensors use GPIO to record data. Typical examples are temperature, humidity or motion sensors that are connected to the PC via GPIO.
  • LED and display control:
    Many embedded PCs use GPIO to control status LEDs or small displays that show the operating status, error messages or other information.

Special features of Windows systems

Some mini industrial PCs run on a Windows basis. In this context, the GPIO interface is controlled by special drivers and the operating system, which provides additional stability and security features. For developers who want to use GPIO under Windows, the official Microsoft site is a highly recommended resource. Here you will find instructions for configuring and programming GPIOs under Windows.

Advantages of GPIO in Mini PCs

  • Flexibility and adaptability:
    This is a universal interface that can be used in a variety of ways โ€“ from simple signals to complex control systems.
  • Cost savings:
    Instead of requiring a separate interface for each external device, several devices can be connected and controlled via GPIO.
  • Compactness:
    GPIO reduces the need for additional interfaces and thus enables compact designs โ€“ ideal for industrial environments with limited space.

What do you need to look out for?

  • Working safely with voltage:
    As the pins are sensitive to voltage fluctuations, the correct voltage (usually 3.3V or 5V) should be ensured.
  • Use of protective diodes:
    Voltage surges can occur in industrial environments. The use of protective diodes or resistors protects the pins from overvoltage and extends their service life.
  • Use of suitable software:
    Simple Python programs enable direct control of the GPIO pins. Many platforms offer SDKs and APIs to make programming easier.

GPIO is one of the most valuable interfaces for industrial and embedded PCs and opens up a wide range of applications. The flexible input and output pins offer an easy way to communicate with external devices and control a wide range of functions. It plays a particularly important role in industry, where flexibility and adaptability are required.

If you are looking for a robust, versatile system for industrial or IoT applications, mini industrial PCs with the general purpose input/output interface are the ideal choice.
Thanks to the numerous possible applications and their adaptability, they are perfect for individual and specific requirements. Of course, our spo-comm Mini-PCs are also equipped with GPIO. If you are interested or have any other questions, please do not hesitate to contact us.

What is PCI and PCIe?

The PCI interface (Peripheral Component Interconnect) was developed in the 1990s as a standard for connecting various expansion cards to a computer system. It enabled efficient communication between hardware components. However, as technological development progressed, the original PCI interface became a bottleneck for modern, high-performance devices.

This is where the Express version comes into play. PCIe (Peripheral Component Interconnect Express) is a further development of the previous technology, which offers much higher data transfer rates and better scalability. While PCI once worked with parallel data buses, PCIe relies on serial data transmission and offers several โ€œlanesโ€ that can be used in parallel. This leads to a drastic improvement in the speed and efficiency of data transmission.

Of course, you will also find one or two PCIe interfaces in our spo-comm product catalog. In addition to this port, our NOVA R680E offers some other interesting features!

Advantages of the interface for mini PCs

  • Higher data transfer rates
    Mini PCs benefit from the high bandwidth of the PCIe interface. Whether connecting a graphics card or an NVMe SSD for lightning-fast data storage, this connection is now the standard for fast, stable connections. The latest version, PCIe 5.0, enables data rates of up to 32 GT/s (gigatransfers per second) per lane, giving Mini PCs unprecedented performance.

    Outlook: It will be even more powerful with the upcoming PCIe 6.0 version, which is already within reach and promises transfer rates of up to 64 GT/s.
  • Flexibility and scalability
    The interface has a modular structure. This means that there are different configurations, such as x1, x4, x8 or x16, which support different numbers of data channels. Mini PCs, which are usually designed to be compact, can thus be flexibly adapted to different requirements without having to compromise on performance.

  • Compatibility and future-proofing
    Another advantage of PCIe technology is its backwards compatibility. This means that older devices with this interface can also be operated on newer PCIe slots. This makes the interface a future-proof solution that is ideal for mini PCs, as these are often in use for many years.

The next generation of data transmission

The next stage in the evolution of the PCIe interface is imminent with PCIe 6.0. This new version not only brings twice the data transfer rates of PCIe 5.0, but also more efficient error correction methods and even lower latency. For Mini PC users who need maximum performance in the smallest possible space, this is an absolute game changer. The newer version will make it possible to transfer even more data in less time, which is a clear advantage especially in data-intensive applications such as 3D graphics processing, machine learning and high-performance computing.

PCIe as a key technology for Mini PCs

The PCIe interface is undoubtedly one of the most important technologies for modern Mini PCs. It provides the necessary bandwidth, flexibility and future-proofing to meet the demands of todayโ€™s hardware. From powerful graphics cards to lightning-fast NVMe SSDs, the right PCIe interface can significantly boost the performance of your Mini PC.

What is a watchdog function?

It is an essential monitoring function that continuously monitors the operation of a system to ensure that it is running properly. If the system fails or hangs due to an error or a software or hardware problem, the device will be restarted or put into a safe state. The name โ€œWatchdogโ€ says it all: like a watchdog, it monitors the entire operation of the system and reacts immediately if something goes wrong.

How a watchdog works

A watchdog controller continuously monitors the systemโ€™s activities. The process works as follows:

  1. Regular check: The system is checked at regular intervals to ensure that it is running properly. This can be done by receiving a โ€œheartbeat signalโ€ โ€“ a regular signal from the operating system or software that informs the watchdog that everything is OK.
  2. Error detection: If this signal is not received within a certain time frame or an error is detected, the controller interprets this as a problem.
  3. Response: The watchdog responds to this error message by restarting the system or taking another predefined action, such as activating a safe system state.

This little companion is particularly useful in areas where a system failure could have serious consequences, such as in industrial plants, medical devices or automation technology.

Why is the watchdog function important for Mini PCs?

Mini PCs โ€“ including our spo-comm computers โ€“ are particularly in demand in areas such as industrial automation, IoT (Internet of Things), machine control and media technology. These applications not only require high computing power, but also exceptionally high availability. This is where the watchdog function comes into play. It ensures that the Mini PC can be operated reliably without failures, which is crucial for the smooth running of processes.

In many cases, a system failure can lead to costly downtime or, in the worst case, cause security breaches. Especially in automated systems or in environments where people depend on the functionality of devices, the watchdog function can save lives and protect companies from major damage.

Watchdog in practice: Applications

  • Industrial automation: In production lines or automated production lines in which machines and devices run around the clock, it ensures that all systems remain stable and react immediately in the event of a system error.
  • IoT devices: Many IoT applications, whether in vehicles or smart cities, require constant monitoring. It ensures that these devices continue to work reliably even after a malfunction.
  • Medical devices: It is also of great importance in medical devices where failures could have serious consequences. For example, the failure of a mini PC in a medical device can be rectified quickly and safely.
  • Digital signage: In areas such as digital advertising or information transmission, the watchdog ensures that content is displayed on screens without interruption.

Advantages of the little helper

  • Increased system stability: Continuous monitoring means that errors are detected at an early stage and the system can be restored quickly.
  • Automatic troubleshooting: The watchdog function automatically takes care of troubleshooting without the user having to intervene.
  • Reliability in critical applications: In many areas, such as industrial automation or healthcare, downtimes are unacceptable. The watchdog ensures that these are minimized.
  • Lower maintenance costs: As the watchdog detects and rectifies errors at an early stage, less manual intervention is required. This saves time and costs for maintenance work.

An indispensable security feature for mini PCs

The watchdog function ensures reliable Mini PCs and ensures that they run stably even in demanding applications. It continuously monitors the system and ensures that errors are rectified quickly before they lead to major problems. For companies that use mini PCs in safety-critical or high-availability applications, the integration of a watchdog is therefore a valuable investment.

In short: This is ARM

ARM is an architecture for microprocessors based on the RISC (Reduced Instruction Set Computing) principle. Since ARM processors work with a simplified instruction set architecture, they are more energy efficient compared to traditional CISC (Complex Instruction Set Computing) processors. ARM processors are designed to consume less power, making them ideal for mobile devices, embedded systems and IoT applications.

How does ARM technology work?

The functionality of the ARM architecture is based on a minimalist design approach in which only the most necessary instructions are implemented directly in the hardware. This allows the processor to work more efficiently, as fewer transistors* are required to perform tasks. Fewer transistors lead to lower power consumption and less waste heat, which makes the ARM architecture particularly attractive for devices that require a long battery life.

ARM processors use a pipeline architecture in which different stages of an instruction are processed simultaneously, enabling high speed with low energy consumption. In addition, these processors often have a modular design so that they can be adapted to the specific needs of a device, which further increases their flexibility and versatility.

ARM technology in mini PCs and embedded systems

The use of ARM processors in mini PCs and embedded systems has increased significantly in recent years. The use of ARM processors enables these devices to work efficiently and save power, making them ideal for the various application areas of Mini PCs.

Embedded systems are computers that are integrated into more complex systems and perform special tasks. Typical areas of use include machine control or IoT applications. ARM processors are perfect for such applications due to their flexibility, scalability and energy efficiency. They enable the continuous further development of embedded systems to perform even more complex tasks while remaining compact and energy-efficient.

Advantages of ARM for mini and embedded PCs

  1. Energy efficiency: ARM processors are known for being particularly energy efficient, which extends battery life and reduces power consumption.
  2. Compact design: The minimalist design of the ARM architecture means that devices can be compact and lightweight without having to sacrifice performance.
  3. Scalability: ARM processors are customizable, so they can be scaled and optimized as needed.
  4. Costs: ARM-based devices are often cheaper to manufacture, which is reflected in lower prices.

Energy efficiency of embedded PCs

Lower power consumption

Embedded PCs use energy-saving processors and special hardware components. These are often adapted to specific tasks and therefore require less energy than conventional desktop PCs. A second advantage is that many of these systems are designed in such a way that they do not require active cooling, which further reduces power consumption. In addition, they often have advanced power-saving modes that minimize energy consumption when the system is not fully utilized.

Another aspect of the energy efficiency of embedded PCs is the ability to adapt them to the specific energy requirements of the respective application. By using low-power processors, which have been specially developed for use in resource-constrained environments, power consumption can be reduced to an absolute minimum. This is particularly beneficial in portable or remote environments where power supply is limited and battery operation is required. In addition, many embedded PCs are equipped with advanced power management features that further reduce not only power consumption but also thermal load. This combination leads to a further significant reduction in energy consumption and increased operating efficiency.

Efficient software

The software for embedded systems is specially optimized to work with minimal resources, which also contributes to energy efficiency. These PCs often run on real-time operating systems that are designed to work successfully and without delay, which also saves energy.

In addition to operating system optimization, many embedded systems are designed to be particularly efficient at application level. This means that the software solutions are often tailored to specific tasks and optimized accordingly so that no unnecessary calculations or processes run in the background. This is a key factor in increasing energy efficiency, as less computing power and memory usage is required. In critical applications where reliability and immediate responsiveness are required, such as in medical technology or industrial automation, software efficiency makes a decisive contribution to reducing overall energy consumption.


Sustainability of embedded PCs

Durability and reliability

Embedded PCs are designed for use in harsh environments and have a longer service life than conventional PCs. This reduces the need for frequent replacement and the associated environmental impact. In addition, the long-term availability of components and spare parts is often guaranteed, which further extends the service life of the devices.

Reduced use of materials

Due to their compact design, embedded systems use fewer materials than conventional computers, which reduces the consumption of resources during production. Some of these systems are modular, which makes upgrades and repairs easier and reduces the need for complete system replacement.

Less electronic waste

The durability and robustness of embedded PCs help to reduce electronic waste. In addition, many of these systems are designed to be easier to recycle as they contain fewer different materials and plastics.

Application scenarios

Embedded PCs are used in a wide range of applications. In industry and automation, they provide advantageous control and monitoring of machines and processes, which can optimize the energy consumption of the entire system. In the area of the Internet of Things (IoT), embedded systems are used to create intelligent and energy-efficient solutions for households and buildings. PCs are also frequently used in a wide variety of vehicles, whether police or customs vehicles, in the development of autonomous driving or the evaluation of measurement data, cameras and sensors.


spo-comm Sidefact

Other important areas of application for embedded PCs are renewable energies and smart grids. Embedded PCs are used in solar systems and wind power plants to monitor and optimize energy production, which increases the efficiency of the systems and minimizes energy consumption. Embedded systems are also increasingly being used in agriculture, for example to control irrigation systems or to monitor environmental parameters, which makes the use of water and energy more efficient. Embedded PCs therefore play a central role in the development of sustainable infrastructures and contribute to the global reduction of energy consumption and environmental pollution.


Embedded PCs are a key component in the development of energy-efficient and sustainable technologies. Thanks to their specialized and optimized designs, they contribute to both reducing energy consumption and environmental impact.

Essentially, we are talking about a slim end device that is designed for accessing central servers or cloud services. In contrast to traditional desktop computers, thin clients do not have extensive internal data processing and storage. Instead, they rely on the resources and computing power of servers to run applications and store data.

Advantages of thin clients

Cost efficiency: As a rule, they are cheaper to purchase and maintain than conventional desktop PCs.
As most computing processes are centralized, companies can also reduce their operating costs. Improved security: As data is stored centrally, it is easier to implement security measures and protect sensitive information.
Centralized access also allows companies to better control and monitor data access. Simple administration: The administration of thin clients is generally simpler and more efficient, as updates, patches and software installations can be managed centrally.
This facilitates the scaling and maintenance of IT infrastructures. Flexibility: Users can access their work environment from virtually anywhere as long as there is a connection to the server. This promotes employee mobility and flexibility and enables companies to implement remote working models.

spo-comm Mini-PCs as thin clients

Our new addition, the ONE H610, is ideal as a thin client, as are the CORE 3 and our all-rounder WINDBOX series. More spo-comm knowledge
