The motor interfaces on the expansion board, if they are motor 1, motor 2, motor 3, motor 4, motor 5, motor 6, the corresponding motors are motor 1, motor 2, motor 3, motor 4, motor 5, motor 6, the left is 1, 2, 3, the right is 4, 5, 6.
Your problem is: motor 1, motor 2, motor 3 interface of motor 1, motor 2, motor 3 does not work, after interchanging the wiring position of the motors, motor 1, motor 2, motor 3, motor 4, motor 5, motor 6, the corresponding motor is motor 4, motor 5, motor 6, motor 1, motor 2, motor 3. then motor 1, motor 2, motor 3 can work normally, then can motor 4, motor 5, motor 6 work normally?
Hint: Do you have sufficient battery power to work yet.
