Motor Driver for Raspberry Pi - Dual G2 High-Power 24V14 - Pololu 3752

This G2 dual high-power motor driver is an add-on board for the Raspberry Pi, featuring a pair of discrete MOSFET H-bridges designed to drive two large brushed DC motors. It has been designed to mount on and plug into compatible Raspberry Pi boards (Model B+ or newer), including the Pi 4. 

The minimum operating voltage for all four versions is 6.5 V, while the maximum operating voltages are given in the above table. The board also includes an integrated 5 V, 2.5 A switching step-down regulator that can be used to power the Raspberry Pi it is plugged into, enabling operation from a single power supply.
The driver’s default configuration uses six GPIO pins to control the motor drivers, making use of the Raspberry Pi’s hardware PWM outputs, and it uses two additional pins to read status outputs from the drivers. However, the pin mappings can be customized if the defaults are not convenient, and pins for current sensing and limiting are accessible on the board for more advanced applications.


The board matches the Raspberry Pi HAT (Hardware Attached on Top) mechanical specification, although it does not conform to the full HAT specifications due to the lack of an ID EEPROM. (A footprint for adding your own EEPROM is available for applications where one would be useful; pull-ups on SDA, SCL, and WP are provided.) It is not practical to use this expansion board with the original Raspberry Pi Model A or Model B due to differences in their pinout and form factor.
  • PWM operation up to 100 kHz
  • Motor indicator LEDs show what the outputs are doing even when no motor is connected
  • Integrated 5 V, 2.5 A switching step-down voltage regulator powers the Raspberry Pi base for single-supply operation
  • Python Library makes it easy to get started using this board as a motor driver expansion board
  • GPIO pin mappings can be customized if the default mappings are not convenient
  • Current sensing and limiting pins are exposed for advanced use
  • Reverse-voltage protection
  • Undervoltage shutdown
  • Short circuit protection
  • Operating voltage: 6.5 V to 36 V (absolute maximum; not intended for use with 36 V batteries)
    • Maximum can be increased to 40 V if the regulator is disconnected (see below)
  • Output current: 14 A continuous
  • Active current limiting (chopping) with an approximate default threshold of 40 A (can be adjusted lower)
This version of the 24v14 motor driver is a partial kit, with connectors included but not soldered in. It can be distinguished from the other versions by its red PCB and the number 100 on top of the six tall silver electrolytic capacitors at the corner of the board.


  • Motor channels: 2
  • Minimum operating voltage: 6.5 V
  • Maximum operating voltage: 36 V (Absolute maximum; higher voltages can permanently destroy the motor driver. The recommended maximum is approximately 30 V, which leaves a safety margin for ripple voltage on the supply line. Disconnecting on-board regulator increases absolute maximum to 40 V. Not recommended for use with 36 V batteries.)
  • Continuous output current per channel: 14 A (Typical results at room temperature with both channels running at 90% duty cycle)
  • Maximum PWM frequency: 100 kHz
  • Reverse voltage protection?: Yes


  • Length: 65
  • Width: 56 mm
  • Weight: 20 g
