4 channel controller

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.


  VCC to Arduino 5V

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