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.
Features
- 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
