Yes – I was intending to write it up along with instructions on how to add my firmware, I will try to do it tonight. The only part I am unsure on is exactly how to access the header on an official opengarage device, I don’t have one myself I have a custom made one using the same components.
According to the schematic the header is at the top of the board but i don’t see any opening in the case to access it. Do you have the device yet?
