I was running the WiFi car example program and was the motor connected to motor port D wouldn’t run.
I knew both my motors were good, so I wondered if the BrickPi wasn’t getting enough power. (I was using a Ravpower 15,000mah battery pack on the 9v setting) I switched from the 9v setting to the 12v setting and ran the WiFi car program again. Motor D still didn’t run and within 2-3 seconds I heard a loud POP.
I tested the battery pack with a voltmeter, it actually outputs 9.6 or 12.6 volts.
I have also noticed a crack in the one of the SN754410NE chips.
Did I just destroy my BrickPi?
