Is there a schematic of the Duo available anywhere?
My reason for asking is twofold:
Firstly, I want to know if the GND of the MIDI IN and USB are directly connected. This is because I want to send messages to the MIDI IN from a microcontroller powered by the Duo’s USB port. So if the GND is shared, I don’t have to connect anything to the MIDI IN’s GND.
Secondly, schematics are cool. I just want to look at it. And maybe if I have a similar question in the future I’ll just look at the schematic
