Pololu Dual G2 High-Power Motor Driver 24v14 Shield for Arduino
This shield makes it easy to control two high-power DC motors with your Arduino or Arduino-compatible board.
Its twin discrete MOSFET H-bridges support a wide 6.5 V to 40 V operating range and are efficient enough to deliver a continuous 14 A without a heat sink.
Details
The drivers offer basic current sensing and current limiting functionality, and they accept ultrasonic PWM frequencies for quieter operation.
The Arduino pin mappings can all be customized if the defaults are not convenient, and the motor driver control lines are broken out along the left side of the shield for general-purpose use without an Arduino.
The G2 family of dual high-power motor driver shields features pairs of discrete MOSFET H-bridges designed to drive two large brushed DC motors. They have the form factor of an Arduino shield, so they can plug directly into an Arduino or compatible board, such as the A-Star 32U4 Prime, but they also break out all of the motor driver pins along the left side of the board to enable use as a general-purpose motor driver without an Arduino.
