We have a problem with one of our Raspberry Pi 3's.
We are using the CamJamEduKit3 Robotics kit and have been writing some code from the associated worksheets to run our motors from the motor driver board.
One one of the Pi's as soon as you switch the battery pack on that powers the motors (via the driver board) one of the motors starts to spin.
I have emailed Mike (CamJam) who has given me the BCM pin numbers for the board BCM 7 and 8 (Motor B), BCM 9 and 10 (Motor A)
I have just had a poke around with a multimeter and BCM 8 and 10 and outputting 2.23 and 3.28v respectively without any code running. Is this a faulty board?
