I have cut the V-USB line on the bottom of my 3.2 and confirmed with a continuity checker it is disconnected. When I power the circuit ONLY externally using this example everything works as expected. When I disconnect the ext. power and plug in the USB the circuit also works. Is this right?
I figured with the VIN cut the pins wouldn't be outputting.
For context, the circuit is for stepper motors with drivers and 24v lines plugged into the drivers (separated from the circuit). The drivers apparently need extremely low power to run so maybe something odd is working by fluke?
