Pololu High-Power Motor Driver 24v20

The Pololu High-Power Motor Driver 24v20 discrete MOSFET H-bridge motor driver

enables bidirectional control of one high-power DC brushed motor.

Small sized 1.8x0.8-inch board supports a wide 5.5 to 40 V voltage range

Enough to deliver a continuous 20 A without a heat sink.
