This DDSM Driver HAT is a motor driver board for DDSM115, DDSM210 and DDSM315 direct-drive servo motors (If you're looking for a board to run the DDSM400, we have a different driver board for that)

The board has an ESP32 microcontroller, supports 2.4GHz WiFi, and offers multiple communication interfaces such as Type-C and UART.

This HAT provides precise motor control with real-time feedback and is suitable for robotics and automation projects. It has a 5V buck regulator for powering Raspberry Pi and supports web control applications, JSON commands, and SDK for easy development.

Note: Motors are NOT included and the only cable included is the USB-C.

Features

• Suitable for DDSM series hub motors such as DDSM115 and DDSM210, onboard 4-channel DDSM115 motor interfaces and 4-channel DDSM210 motor interfaces
• Provides 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
