Request: Electronics schematics for various PCBs in kit #22

Open ssnover opened 2 years ago

ssnover commented 2 years ago

Hi there, I recently bought and assembled this kit with the intention of implementing many of the behaviors in Rust. It'd be great if there were PDFs with the schematic diagrams or at least a table explaining the pin out on the PCB and how it aligns with Raspberry Pi header pins. I scanned through the repo and the documentation here: https://docs.sunfounder.com/projects/picar-4wd/en/latest/index.html and couldn't find it.

Thanks for the cool kit!

So far I've deduced that most of the peripheral work seems to be done by the AT32F415 microcontroller which exposes functionality over I2C. Is that interface documented anywhere? Is it possible to program an application onto the microcontroller from the Raspberry Pi (and a binary for the board functionality it currently has if I wanted to go back to what it shipped with)?
