About this project

This simple USB to UART bridge is based off the popular and pretty common CH340C usb to serial chip. It also has an independent +3.3V regulator at the bottom of the PCB and has a type C port. Every single pin of the ch340c IC has been expanded in order to make full use of it or to possibly reconfigure it.
