Standalone Manual Test of MMU2S Unit?
Does anyone know if it is possible to do a standalone bench test for the MMU2S unit. Something like connect to a bench supply, press manual buttons to check for simple operation?
I have had a bit of an accident while testing a modification and damaged my MK3S Einsy board (terminally), I want to see if it has taken the MMU2 control board with it. I have supplied it with 24V using a bench DC power supply, no flashing lights. Do I need to do anything with the signal wires before it will boot, or have I just proved it is dead too?
Is there any documentation for the MMU2S control unit, say on GitHub that might help with the testing? Couldn't find anything but maybe I didn't look in the right places.
Any help much appreciated.

Hi,
if they didnt change the connection on the MMU2s you need to connect the 5V Supply also. The 5V are on the cable with the com port.
You have to look at the schematics. I soldered a diode to the board to supply it with 5v from USB.

Thanks for replying Chris____.
Looking at the schematic from Github, is connector J1 (top left corner of the schematic) the connector for the 4-wire 5-pin cable to the Einsy? Could you not connect +5V and GND at J1?
What is the diode for, and which one did you use?
