U7

U7 got fried for some reason :(

I just got my Dagu 4 Channel Motor Controller, already a small part gave some smoke and one motor channel is not working anymore.

All four wheels were turning at the same time before the channel4 got fried.

Connections:

  VCC to Arduino 5V

4 PWM on the motor controller to 4 PWMs on the Arduino uno.
