This add-on board makes it easy to control two high-power DC motors with a Raspberry Pi. Its twin discrete MOSFET H-bridges support a wide 6.5 V to 30 V operating range and are efficient enough to deliver a continuous 22 A without a heat sink. The drivers offer basic current limiting functionality, and they accept ultrasonic PWM frequencies for quieter operation. The default pin mappings make it easy to get started, but they can be customized for more specialized applications. This version ships as a partial kit; all surface-mount components are installed, but the included through-hole connectors are not soldered in.

Operating voltage: 6.5 V to 30 V (absolute maximum; not intended for use with 24 V batteries)
Output current: 22 A continuous
Active current limiting (chopping) with approximate default threshold of 60 A (can be adjusted lower)

This is the 18v22 motor driver, which is a partial kit; connectors are included but not soldered in. It can be distinguished from the other versions by its black PCB and the number 150 on top of the six tall silver electrolytic capacitors at the corner of the board.

Dimensions

Size: 65 mm × 56 mm
Weight: 20 g. Without included connectors and mounting hardware.

General specifications

Motor channels: 2
Minimum operating voltage: 6.5 V
Maximum operating voltage: 30 V. Absolute maximum; higher voltages can permanently destroy the motor driver. Recommended maximum is approximately 24 V, which leaves a safety margin for ripple voltage on the supply line. Not recommended for use with 24V batteries.
Continuous output current per channel: 22 A. Typical results at room temperature with both channels running at 90% duty cycle.
Maximum PWM frequency: 100 kHz
Reverse voltage protection?: Y
Partial kit?: Y
