STM32F103 24-Channel Servo Control Board

Q: Why I cannot control servo by external serial port, I mean when I use BT module or by arduino Uno serial port? I can do it through pc's serial monitor.

Hello, it's for the baud rate setting. Have you noticed the baudrate setting switch on the corner of the board. Is it in the right place, e.g. if your code is 115200, then the 3 switchs should be in the position as:A1, B1, SERIAL. Besides, the switch are not good to use, you might need a little strenth to poke it from one side to the other side to make sure it is connected firmly. We will update the switch in the next version.

1. Install Driver

It requires installing the driver when you use it for the first time.

2. How to drive the board from Serial port

3. Example Code for Arduino-Wireless Communication

In this section, we will use Arduino IDE to control the servo via wireless communication. Users can learn how to use wireless modules (e.g., Xbee, APC220) with the Veyron Servo Driver.

4. Example Code for Arduino-Servo Control

In this section, we will use Arduino IDE as a Serial port communication tool to control the servo. Users can learn how to send commands to the Veyron Servo Driver to control the servo's position.
