Features: 1. The four-channel encoder motor driver module integrates a high-performance single-chip coprocessor, which can seamlessly connect with multiple controllers such as MSPMO, STM32, and through serial port or IIC communication, simplifying the driving process. 2. Only four connecting wires are required to achieve efficient communication with the main control unit, so as to easily control the motor and obtain encoder data, reduce the number of wiring and reduce the difficulty of operation. 3. At the same time, it supports driving most Hall encoder TT motors, 520/310 and other DC reduction motors on the market, which is an ideal choice for electronic competitions and robot car DIY. 4. The driver board has a built-in high-performance STM32F103RCT6 coprocessor, which supports driving 4 motors and obtaining encoder data, communicates with the external master through IC or serial port to receive drive instructions, and synchronously transmits encoder, battery voltage and other data to the master.
