Is adding a Rpi4ib an hassle or can a total noob like me handle it? Of course the drill of the back plate might be an issue but I can find somebody to take careof this part of the job.
Hi
There is a GPIO socket on the ethernett/usb PCB for the inverted RPi to plug into. Also that you have the SMPS (Black box next to the transformer) this powers the RPi through the GPIO socket. Other than that, cutting the holes is about all you need do. There are a couple of stand offs to locate the RPi.
The main thing is if you have the right power supply, check my picture in the first post, you can see the Black box SMPS above left of the Tranny. If you don't have this on your supply board, you will also need to upgrade to this PSU board.
