In addition to the single-board computer, you need a few other components to
operate the Raspberry Pi. Since no power supply unit is integrated on the
board, an external power adapter with the appropriate voltage and power can
be connected to the mini computer via the USB socket. A monitor is required
for graphic output. The keyboard and mouse for controlling and operating the
device can be connected via USB.
Basically, there is no fixed operating system for the Raspberry Pi. The
computer can run with various operating systems via a memory card that is
inserted into the existing memory card slot. It is recommended to use the
special Linux distribution Raspbian, which is based on Debian Linux. The
latest Raspberry models are also compatible with Windows 10. However, a
special small device variant of Windows 10 is required.
