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 and H2 versions that we recommend over these original drivers as they are better in a number of different ways.
The following table provides a general comparison of the G2 and H2 drivers, which are available in six single-channel versions and eight dual-channel versions. Four of 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 other four dual-channel drivers are in the form factor of a Raspberry Pi HAT and compatible Raspberry Pi boards (Model B+ or newer). The single-channel G2 drivers all have the same form factor except for the highest-power 24v30, which is larger to accommodate the much larger MOSFETs. We also have a higher-voltage, single-channel H2 high-power motor driver with the same form factor as the single-channel G2 drivers, but the control interface and some aspects of the operation are different.

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.
