Dual G2 High-Power Motor Driver 18v18 for Raspberry Pi is not working properly

Dear Support,

I am trying to control two motors by connecting a 14.8V LiPo battery to this motor driver.
The rotation speed of the motor connected to M1 changes, but the direction of rotation does not change. The motor connected to M2 does not rotate. Also, when using M2, the yellow light will not light up.


Can you post pictures of your setup showing how everything is connected and close-up pictures showing both sides of the Dual G2 High-Power Motor Driver board? It sounds like you might have two separate issues. If you swap your motors, does the problem follow the motor or stay with channel 2? Also, what code are you using?
