USB to dual serial port based on CH554

 
Overview

USB to dual UART based on CH554G

Compatible with ch551/ch552/ch554

Use software to simulate UART and lead out DTR and RTS at the same time, which can be used as an automatic dropper for esp8266/esp32
The firmware is modified based on https://github.com/diodep/ch55x_dualserial . The io ports of DTR and RTS are changed and two breathing lights are added. DTR and RTS will be invalid when using the original firmware.

There may be something wrong with the .hex file in the attachment. It is best to use .bin to burn it.

Wait until you have a chance to use the board for free before changing the code.

Note that this thing needs to be compiled under linux
