[0002] The motor driver board is an electronic device used to control the operation of the motor. It usually includes components such as the motor driver chip, power amplifier, protection circuit, interface circuit, etc. The motor driver board is responsible for receiving instructions from the main controller and controlling the motor's speed, direction and other parameters by driving the current and voltage required by the motor.
