【Overview】
[] DDSM400 hub motor driver board

[] Designed specifically for DDSM400 hub motors, integrated with ESP32 and control circuit

[] Six DDSM400 hub motors can be controlled simultaneously through the ESP32 serial port or USB interface,Hub motor SDK is provided to facilitate secondary development by users

【Product Features】
[] Used to drive DDSM400 wheel hub motor, with 6 DDSM400 motor interfaces on board

[] Based on ESP32-WROOM-32 module, supports multiple wired and wireless communication methods, supports JSON command interaction, and is convenient for host computer control

[] Provides easy-to-use DDSM400 wheel hub motor control routines and SDK

[] Integrated WEB application for controlling and setting DDSM400 wheel hub motor, convenient for debugging

[] Can communicate directly with wheel hub motor through Type-C interface

[] Supports installation of Raspberry Pi, integrated 5V buck regulator circuit, can power Raspberry Pi, communicate through GPIO serial port, and reduce wiring complexity

Parameter

【Main application indication】
[] It can be used to drive the DDSM400 series wheel hub motor and obtain feedback information from the motor.

[] The host computer can control the wheel hub motor and obtain feedback information in JSON format through JSON instructions, which reduces the difficulty of use and helps users with secondary development.

[] Supports multiple communication methods and is easy to integrate into 6 × 6 and 4 × 4 robot projects.

For display only, please refer to the configuration list for specific configuration.
【Supports controlling multiple wheel hub motors】

Since the power of the hub motor is relatively large, when too many hub motors are used, it is necessary to consider whether the power supply solution can meet the requirements.

[] Wired control method——Control via USB interface

[] Use 115200 baud rate to communicate with the ESP32 of the driver board

[] Set and control the hub motor by sending JSON format commands

[] Get information feedback in JSON format

[] Provide Python routines, you can use Python programs in the host computer to control the hub motor

[] When connected to a Type-C port marked with DDSM and the switch is in the USB position, it can communicate directly with the hub motor. It is suitable for users who have the ability to independently develop driver programs.

[] Wireless control method - control via Web application

[] After the hub motor driver board is powered on, it will automatically establish a hotspot for users to connect to.
[] The web application supports cross-platform use and can be used through mobile phones, tablets, and PCs.
[] Using this web application, you can send JSON commands to the hub motor driver board.

【Support installation on Raspberry Pi】
[] Applicable to motherboards such as Raspberry Pi 5 / 4B, can power the Raspberry Pi,Communicate through the GPIO serial port of the Raspberry Pi, reducing wiring complexity

【ESP32 Master Controller】
[] Rich information, convenient for secondary development

[] Built-in WIFI and Bluetooth, supports ESP-NOW, can remotely control and debug the motor
