Powerful computers include the mini Raspberry Pi. It is available in several configurations, including the latest Raspberry Pi 4 series. Raspberry also includes the open source Raspbian operating system.
Mini computers have many advantages, one of which is mainly their size. You can place them in places where a classic desktop computer could not exist. We use them, for example, during video projections, where smart TVs often come into play these days. Very interesting is their use, for example, in smart homes, where Smart Home technology, software applicable to the Raspbian system, can be used.
