Dual G2 High-Power Motor Driver 24V14 are add-on boards for the Raspberry Pi, featuring pairs of discrete MOSFET H-bridges designed to drive two large brushed DC motors. They are designed to mount on and plug into compatible Raspberry Pi boards (Model B+ or newer), including the Pi 3 Model B and Model A+. Its twin discrete MOSFET H-bridges support a wide 6.5 V to 36 V operating range and are efficient enough to deliver a continuous 14 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.
