USBee32-S2 : ESP32-S2 Hardware Design



This repository contains hardware design files and datasheets for the ESP32-S2. This is an open source ESP32-S2 based PCB with breakout ports for both USB - Type A and USB - Type C.
  • Small form factor of 68.4mm x 27.9mm
  • Four layered customly designed general purpose Development board
  • Uses ESP32-S2-WROOM RF module
  • Breakout ports for both USB - Type A and USB - Type C
  • Uses CH340C which gives a high current output converting USB to UART logic
  • Powering modes for the ESP - Either can be used
    • USB - A: Using a USB A Male Cable
    • USB - C: Using a USB C Male Cable(Typical Mobile charger cable)
    • VI Pin: Supplying this GPIO pin with external 5V
  • Has a On - board debuggable Neopixel (RGB Led)
  • Has an ESD protection device which protects the circuit from electrostatic discharge and prevents malfunction/breakdown of the device
  • Uses MCP73831 for charging LiPo battery
  • Can use it as a power/communicating device for a joystick/ game controller
  • Space efficient PCB with integrating majority components in SMD type package
