An H-bridge capable of controlling one DC motor in both directions or two unidirectional motors at voltages from 4.5 to 44 V and continuous currents up to 1.3 A. The module offers three operating modes (PH/EN, IN/IN, half-bridge), built-in current limiting and measurement, and protection against overheating, overload, undervoltage, and reverse polarity. Its compact design, flexible logic power supply (1.8–5.5 V), and simple control make it ideal for robotics, automation, and hobby projects. Pololu 4971
