The Motor Driver HAT with Extended Fittings - Raspberry Pi RoHS, manufactured by Waveshare, is an electronic driver board designed to be used with Raspberry Pi models. It is powered by the Raspberry Pi’s 5V and 3.3V power sources, making an additional power source unnecessary. It provides protection against over temperature, overvoltage, and overcurrent. It also features an external power port that can control 4 DC motors or 2 stepper motors. The hat provides extended fittings for both power and control, making it a powerful and versatile HAT suitable for many types of projects. The HAT is also RoHS compliant, ensuring safe and compliant operation with the Raspberry Pi platform.
