Here’s the latest I have for the Jackpot V2 schematic. I believe this is current and correct for the J2 boards that are in the shop.
NOTE: There may have been a pulldown or pullup resistor added as a manual rework that is not reflected yet in the schematic! (It’s already in there- R56). Ryan is on top of it.
As you can see, both VMOT and 5V are present and available just as they are on Bart’s expansion module.
If you are building a CYD, you must only wire 5V to the system.
If your are building an M5 stack, then you can use either (I would prefer VMOT for that application).
