The DC Motor Driver HAT is a Raspberry Pi add-on board that drives up to two DC motors via I2C. Built around the TB6612FNG motor driver chip with 1.2 A continuous current per channel (2 A peak), it supports both standard DC motors and motors with encoders through the on-board encoder interface.
An STM32 microprocessor handles command processing from the Raspberry Pi and converts instructions into motor drive signals. The board accepts 7–12 V input and communicates via I2C, making it straightforward to integrate into robotics and motion control projects.

Jargon buster
Plain-language definitions for the technical terms used above.
- encoder
- A device attached to a motor or shaft that reports movement, such as rotation steps or position. In a pump system, an encoder can help measure or control how much the motor has turned, which affects how repeatable the watering amount can be.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- motor driver
- An electronic circuit that lets a low-power controller switch and control a motor that needs more current than the controller pins can safely provide. Checking motor driver support matters because pumps and motors usually cannot be connected directly to a microcontroller output.
- STM32
- STM32 is a family of microcontroller chips commonly used in embedded electronics. Knowing a product uses an STM32 can help when looking at firmware updates, pin connections, or low-level serial control options.
