Pololu G2 High-Power Motor Driver 24v21

Pololu item #: 2995

This discrete MOSFET H-bridge motor driver enables bidirectional control of one high-power DC brushed motor. The small 1.3″ × 0.8″ board supports a wide 6.5 V to 40 V voltage range and is efficient enough to deliver a continuous 21 A without a heat sink. Additional features of this second-generation (G2) driver include reverse-voltage protection along with basic current sensing and current limiting functionality.


Size: 1.3″ × 0.8″
Weight: 5.0 g1

  • 1 – Without included connectors.
  • 2 – Absolute maximum; higher voltages can permanently destroy the motor driver. Recommended maximum is approximately 34 V, which leaves a safety margin for ripple voltage on the supply line.
  • 3 – Typical results with 100% duty cycle at room temperature.
