supports multiple hub motors control

Controlling 6-ch DDSM400 hub motors

Controlling 4-ch DDSM400 hub motors

* Due to the high power of the hub motors, it is necessary to consider whether the power supply solution is enough when using too many hub motors

Wired control Mode via USB cable

• Using 115200 baudrate to communicate with ESP32 of the driver board
• Supports sending commands in JSON format to set up and control the hub motors
• Obtains feedback information in JSON format
• Provides Python demo for controlling the hub motors on the host controller

• When connecting to the Type-C port with DDSM mark and switching to USB control, you can directly communicate with the hub motors. Suitable for users who can independently develop the driver program.

Wireless control Mode via Web application

• The DDSM driver HAT will automatically establish a hotspot after powering on
• Allows users to connect and control the driver HAT via mobile phones, Tablets and PCs with the cross-platform Web Application
• Supports sending the JSON commands to the driver HAT via Web Application
