I did not need to use it until recently, 2024-09. Basically a special 'hat' is mounted on a standard Raspberry Pi 4, the smallest memory unit type being sufficient (2 GB). The kit was complete with all the required parts, such as the hat, Raspberry PI, a case, small OLED display and various cables. The PiKVM is V3 HAT with RPi V4 2GB.
