Serial port to 8-channel analog servo driver board

Overview

The software and hardware are open source. The software is improved by using the official library function of STC8H. The open source link of the software: https://pan.baidu.com/s/1d5P6o7pNbrETi4eQlHsSIQ?pwd=l3gi Extraction code: l3gi This project is a serial port input to 8 PWM output drives the analog servo driver board. The main control is STC8H1K08. It also provides battery voltage output (11.7V), 5V voltage output (using AMS1117-5.0), 3.3V voltage output (using AMS117-3.3), grounding port, 8 The servo is powered by four channels (4 channels of 7806 power supply) while retaining a serial port interface, and the power interface is XT60.
The serial port input format of the software part is 0x57 0x4a 0x** 0x** ... ten digits in total, and the input is the angle value (hexadecimal)
