Keyboard core board

Overview

!!!Note: Please select a board thickness of 0.8mm when creating the board!!!!!
Hardware resources:
Built-in 1 I2C channel connects to a high-capacity EEPROM for convenient storage of key mappings, lighting, macros, etc.;
1 external I2C channel can drive an OLED screen or other peripherals;
3 SPI channels are used for keyboard reading, lighting display, and a 2.4G transmission module;
2 ADC channels can be used for Hall effect joysticks;
2 serial ports can be used for communication with other expansion modules;
an ST-Link interface is provided for easy user downloading;
there are 4 0-ohm resistors on the board for configuring BOOT0 and BOOT1, please remove them as needed;
this board can also be used as a core board for embedded learning, and its purpose can be changed through different expansion boards.
