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
