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 18 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 fully assembled with connectors soldered in.

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 30 V (absolute maximum; not intended for use with 24 V batteries)
Output current: 18 A continuous
Active current limiting (chopping) with approximate default threshold of 50 A (can be adjusted lower)

This version of the 18v18 motor driver is fully assembled, with a 2×20-pin 0.1″ female header (for the Raspberry Pi interface) and a six-pin strip of 5 mm terminal blocks (for board power and motor outputs) soldered in. It can be distinguished from the other versions by its red PCB and the number 150 on top of the six tall silver electrolytic capacitors at the corner of the board. (See item PO3750 for a kit version with connectors included but not soldered in.)

Dimensions
Size: 65 mm × 56 mm
Weight: 30 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: 18 A. Typical results at room temperature with both channels running at 90% duty cycle.
Maximum PWM frequency: 100 kHz
Reverse voltage protection?: Y
