Hi, I really like the look of the Explorer HAT for driving motors and I’m interested in using it with some cheapo DC motors. I’m a bit confused about the power arrangements on the Explorer HAT, though… I can see that it’s 5V at 200mA per motor (which I think will be OK with most DC motors which seem happy with anything between 3 and 6v).
However, I was wondering if it’s possible from me to provide power from a separate battery pack for just the motors (e.g. 3 x AA batteries). I’ve read something that it suggested it was possible, but can’t see where the power supply would connect on the HAT pinouts.
TBH, it’s probably not a problem if it’s not possible, but I was just curious!
