moto:bit and current limit

Post by slylock » Fri May 18, 2018 10:44 am

I'm trying to use the Moto:bit (motor controller for BBC Micro:bit), with 393 motors from VEX, and I believe I'm running into a current limit of some kind. I'm using 7.2V, and smaller motors work fine, but these 393 motors just buzz a little bit, and very occasionally turn on. The buzzing makes me think there is some very fast fuse opening and closing rapidly. Anyone know a precise current limit for the moto:bit?
