Raspberry Pi 4B with Prusa MK3s / Einsy RAMBo headers

The guide below describes how to connect a Raspberry Pi 4B to the Prusa i3 MK3s main board (Einsy RAMBo) board with its builtin RPi headers and an additional step-down / buck converter. The buck converter is necessary, since the Einsy headers do not provide enough amps to power anything bigger than a Raspberry Pi Zero W.
