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 as a partial kit; all surface-mount components are installed, but the included through-hole connectors are not soldered in.
