Auto pHat External Motor Power

Hello,

I need to power to 9V motors (LEGO NXT motors) with an auto pHat. From the schematic, it looks like I can just solder headers onto the external power pins and put 9V there and the current protection circuits will keep the 9V out of the 5V paths. Is my understanding correct?

Thanks!

Yep, you got it. :slight_smile:

Use the MTR 5-9V pin and ground and the motors will see that as a supply rather than 5 volts. The reverse current protection circuit will keep 9 volts from flowing back into the 5 volt supply.
