The Waveshare Motor Driver HAT is a compact and efficient motor control expansion board designed for Raspberry Pi projects. Featuring I2C communication, it simplifies motor control while minimizing GPIO usage. The board integrates the PCA9685 PWM controller and TB6612FNG dual H-bridge motor driver, enabling precise speed and direction control of two DC motors. With support for stackable addressing, up to 32 boards can be connected for large-scale robotics applications. An onboard 5V regulator provides up to 3A output and allows battery-powered operation through the VIN terminal. Compatible with Raspberry Pi Zero, Zero W, Zero WH, 2B, 3B, and 3B+, this HAT is ideal for robotics, automation, educational projects, and smart vehicle development. Its efficient design ensures low heat generation and reliable motor performance. Features: Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards I2C controlled, by setting 5 address jumpers, it is stackable up to 32 this modules Onboard PCA9685 chip, provides 12-bit hardware PWM to adjust motor speed Onboard TB6612FNG dual H-bridge motor driver, high efficiency, low heating Integrates 5V regulator, up to 3A output current, can be powered from battery through VIN terminal Reserved I2C control pins, allows to work with other control boards Comes with development resources and manual (examples in BCM2835, wiringPi, and python) Specifications: Power supply: 6V~12V (VIN terminal) Logic voltage: 3.3V PWM driver: PCA9685 Control interface: I2C Motor driver: TB6612FNG Dimension: 65mm x 30mm Mounting hole size: 3.0mm Weight: 18 g Useful Link: https://www.waveshare.com/wiki/Motor_Driver_HAT Package Includes: 1 x Waveshare Motor Driver HAT for Raspberry Pi, I2C Interface 1 x RPi screws pack
