CP2102 serial port module with ESP32 auto-download and dual USB ports

Overview

Essentially, it's a CP2102 to serial port module
with dual micro USB and Type-C inputs (both can be soldered, but only one can be used at a time). It basically works with any available cable
. An ESP32 auto-download circuit is added for ESP32 serial programming
. Separate DTR and RTS signal lines are provided for when the auto-download circuit isn't needed.
It offers 5V and 3.3V power supplies; the 3.3V is provided by an AMS1117, offering strong power rather than the weak 3.3V rectifier inside the CP2102.
