This DDSM Driver Board is a motor driver expansion board that lets you control up to six DDSM400 servo motors simultaneously, which is ideal for a variety of robotic projects (If you're looking for a board to control DDSM115, DDSM210 or DDSM315 motors, click here). It connects to a Raspberry Pi through its integrated 5V buck regulator circuit and a GPIO 40-pin header connector. The board is built around the ESP32-WROOM-32 module, with multiple wired and wireless communication methods. You can also send JSON commands for easy motor control. The motors can be used via the ESP32 UART or the Type-C USB port, making it easy to integrate with your system. The board also comes with motor control demos and an SDK.
