CH340C USB TO UART BRIDGE

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.
