Overview

A small project based on ESP32, including different Fn modes, and certain modifiable functions for the background lighting effect and OLED display. Welcome to discuss and exchange!
After comparing and referring to some existing open source chip solutions: NRF52832, STM32+Bluetooth chip, etc., we finally decided to use the ESP32 Bluetooth solution instead of USB+Bluetooth dual mode.
Attached is a functional description along with all PCB and code.
