The schematic diagram is modified based on https://oshwhub.com/hearme/ke-zhi-hua-xiao-xuan-niu-pad , modify the matrix, add oled, remove 5050rgb, remove monochrome LED, add 3528 reverse sticker rgb.
There is no positioning plate installed in the picture, and the RGB is a bit overflowing.
Thank you classmate Wang Defa

If you have any questions, please come to me at station b.
A few points of disclaimer: The wiring is lacking, but the actual tests are all ok. Don’t criticize me for pad drilling, poor wiring, etc. I am open source and let you rewire it yourself.
Due to firmware size limitations , the fourth layer needs to be set in via to be effective. OLED has no display, it is recommended to put the power off button, keyboard reset button, etc.
Turn off mouse keys
New lite firmware will automatically clear eeprom, F24 implicitly clears eeprom. Suitable for matrix confusion and rgb confusion (there is a problem with the new version of via key mapping)
The firmware in the compressed package is normal firmware and will not be cleared automatically.

The r3r4 resistor is 22 ohms, not 22k. Wrong writing

A self-restoring insurance has been added to the pcb, and the schematic diagram and BOM have not been updated (be sure to clean it after soldering, some soldering oil conducts electricity, causing the main control to burn)
