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.

Parts needed

• Raspberry Pi 4B
• Step-down converter (LM2596)

1. Download the client-information and move it to /usr/local/bin/client-information:

   wget https://gist.githubusercontent.com/frdmn/5eeebc05c61c7a00450aee8b81be824c/raw/520d3e9ae9ec80710344119e1780939fa843130b/client-information -O /usr/local/bin/client-information
   bash +x /usr/local/bin/client-information
   

2. Configure the scheduler to periodically run the script:
