Pololu High-Power Motor Drivers

The High-Power Motor Driver family started with nine original members that are still available below, but we now have second-generation (G2) versions that we recommend over these original drivers as they are better in a number of different ways.

There are four versions of the single-channel G2 high-power motor drivers that share compatible pinouts, and four versions of the dual-channel G2 high-power motor drivers that share compatible pinouts. The dual-channel drivers have the form factor of an Arduino shield, but they can also be used with other controllers as general-purpose motor drivers. The following table provides a comparison of the G2 drivers:

Dual G2 High-Power Motor Driver 24v14 Shield 14 A 40 A

Pololu G2 High-Power Motor Driver 24v21 and 24v13.

Pololu Dual G2 High-Power Motor Driver 24v18 Shield for Arduino.

Pololu Dual G2 High-Power Motor Driver 24v14 Shield for Arduino.

The dual-channel G2 drivers are also available in the form factor of a Raspberry Pi HAT for easy use with a Raspberry Pi.

Note: As an alternative to these motor drivers, our Simple Motor Controllers have similar power characteristics and offer high-level interfaces (e.g. USB, RC hobby servo pulses, analog voltages, and TTL serial commands) that make them easier to use for some applications.

Quantity:

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 30 V operating range and are efficient enough to deliver a continuous 22 A without a heat sink. 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.
