Features The 2-channel DC motor driver board is designed based on the Raspberry Pi interface, and is suitable for Raspberry Pi Zero/Zero W/Zero WH/2B/3B/3B+. The DC motor driver board is controlled using the I2C interface, and the driver can connect up to 32 modules by changing 5 address jumpers. Onboard PCA9685 chip, the DC motor driver board can output 12-bit hardware to PWM control the motor speed. The onboard TB6612FNG dual H-bridge motor driver chip works efficiently and does not generate heat easily. I2C control interface is reserved for easy connection with other main control boards. This is a motor driver board specially designed for Raspberry Pi. Using I2C interface control, this module can drive 2 way DC motors at the same time. A good choice for DIY smart car.
