Connecting and powering Raspberry Pi to a Prusa
Channel: Ricks Gadgets
Date: 2021-01-26

I will go over the final build of my Prusa Clone printer. I will show the enclosure I use to house the Raspberry PI 3. The wiring setup from a buck converter to power the PI. And then the serial connections from the PI to the Einsy board. This will give you a Pi that is powered by the Prusa power supply and connected without the use of a USB cable.
