Kinda weird that I don't see any exposed gpio pins on the board? The SoC has "up to 170" gpio pins, and especially it has those fancy PRUSSes in there, so feels like huge missed opportunity to not expose any of that?
The reason the SoC says "up to 170" as they are multiplexed with the ethernet, display and camera interfaces, so since this board has all 3 there are likely not many GPIO actually left to pin out
In the block diagram I don't see any of those exposing GPIO.
Nobody's gonna drive a CNC machine with this, that's for sure.
