Pololu G2 High Power Motor Driver 22A, 6.5V-30V for Raspberry Pi

• Can control two high-power DC motors with a Raspberry Pi 4 B 8G Computer Board(not included)
• Operating voltage: 6.5 V to 30 V (absolute maximum)
• Output current: 22 A continuous
• Integrated 5 V, 2.5 A switching step-down voltage regulator
• PWM operation up to 100 kHz

This Pololu G2 High Power Motor Driver 22A, 6.5V-30V for Raspberry Pi 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 22 A without a heat sink. The driver offers basic current limiting functionality, and accepts 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. It is designed to mount on and plug into compatible Raspberry Pi boards (Model B+ or newer), including the Pi 3 Model B and Model A+. The board also includes an integrated 5 V, 2.5 A switching step-down regulator that can be used to power the Raspberry Pi it is plugged into, enabling operation from a single power supply
