This is a driver board for the DDSM series direct drive servo hub motors, featuring 4×DDSM115 motor interfaces and 4×DDSM210 interfaces, integrated with an ESP32 and hub motor control circuit. We have open-sourced the hub motor control demos and the JSON communication interface. Users can connect via USB and use a host computer to send JSON-formatted commands to control the hub motors and receive JSON-formatted feedback (such as motor current, speed, temperature, etc.). Users can also perform secondary development, using it as a slave controller in robotic projects.

Key features
  • Suitable for DDSM series hub motors such as DDSM115 and DDSM210, onboard 4-ch DDSM115 motor interfaces and 4-ch DDSM210 motor interfaces
  • Provided DDSM hub motor control demo and SDK, easy to use
  • Supports multiple wired and wireless communication modes, supports JSON command interaction for easier control
  • Supports connecting to Raspberry Pi, powering the Pi via integrated 5V buck regulator circuit and communicating through GPIO UART interface, neat cable management
  • Integrated web application for controlling and setting the DDSM hub motors, more convenient for debugging
  • Supports controlling the DDSM hub motors directly via onboard Type-C port
