The Pololu Dual G2 High-Power Motor Driver 24v14 is a Raspberry Pi expansion board that can independently control two brushed DC motors at up to 14A continuous per channel. It mounts directly onto the Pi's 40-pin GPIO header in the HAT form factor and includes an integrated 5V 2.5A step-down regulator to power the Pi from the motor supply — enabling single-supply operation.
This is the fully assembled version with the 2×20-pin female header and 5 mm terminal blocks already soldered. A Python library is available for quick setup.
Key Features
- Dual Motor Control – Two independent H-bridge channels
- 14A Continuous Output – Per channel, with active current limiting (default ~40A chopping threshold, adjustable lower)
- Wide Voltage Range – 6.5–36V motor supply (up to 40V with regulator disconnected)
- PWM Up to 100 kHz – Smooth, quiet motor control
- Integrated 5V 2.5A Regulator – Powers the Raspberry Pi from the motor supply
- Motor Indicator LEDs – Visual feedback on output state
- Current Sensing – Exposed current sensing and limiting pins for advanced use
- Built-In Protections – Reverse-voltage protection, undervoltage shutdown, short circuit protection
- Customisable GPIO Mapping – Remap pins if defaults conflict with other hardware
Specifications
- Operating Voltage – 6.5–36V DC (absolute max; not for 36V batteries)
- Output Current – 14A continuous per channel
- Current Limit – ~40A default chopping threshold (adjustable)
- Regulator Output – 5V, 2.5A
- PWM Frequency – Up to 100 kHz
- Form Factor – Raspberry Pi HAT mechanical spec
Note: Compatible with Raspberry Pi models that use the 40-pin GPIO header (A+, B+, Pi 2, Pi 3, Pi 4, Pi 5). Not compatible with the original Model A or Model B due to pinout and form factor differences.
Ideal For
- Raspberry Pi-controlled robots and rovers
- Dual-motor drive systems
- Motorised platforms and CNC projects
- Automated mechanisms requiring high-current motor control

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- 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.
- Headers
- Rows of connector contacts on a fixed pitch (commonly 2.54 mm) used to link a board to a breadboard, jumper wires, or another board. They come as male pin headers and female socket headers; when a module ships with pre-soldered headers it can be used straight away, whereas bare pads require soldering the pins yourself.
- 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.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
- Short circuit protection
- A safety feature that helps protect the device if its output or wiring is accidentally connected in a way that causes excessive current flow. This matters in automation wiring because mistakes or damaged cables can otherwise destroy the sensor or power supply.
