I have attached the Dual VNH5019 Motor Driver Shield to my board, that is full compatible with Arduino Mega 2560, as shown on the user guide. I wanted to power the Polulu 70:1 Metal Gearmotor 37Dx70L mm with 64 CPR Encoder. Shield and arduino are powered together using the Lipo 14,8 V battery.
After I attached one motor with the shield and started the Demo programm, i got the error (“M2 fualt”) in serial monitor. If I disable the stopIfFault() the serial monitor just says the current on M1 is 0.
If I attached the second motor, I also got the error (“M2 fualt”).
Could you please help me and say what i do wrong?
