Pololu High-Power Motor Driver 18v25

The Pololu High-Power Motor Driver 18v25 discrete MOSFET H-bridge motor driver

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

The little 1.8x0.8-inch board supports a wide 5.5 to 30 V voltage range

Efficient enough to deliver a continuous 25 A without a heat sink.
