Kaiku Keycool84 three-mode excellent connection keyboard

Overview

This project is a three-mode wireless keyboard PCB, and the shell is suitable for Kaiku KC84.

The wireless adopts Logitech K375s main control, supports all native functions of K375s, supports U-Connect, Bluetooth, Flow, multi-device and other features.

The wired aspect uses STM/APM32F401CCU6 master control and uses QMK firmware. Uses 86 WB2812B lamp beads and supports RGB control.

Used in conjunction with the charging pad, no manual switching is required, automatic switching between wireless mode and wireless mode

Current progress: Youlian has been tested and is triggered by all keys. I haven't had time to test the cable yet, the firmware has been compiled, the cable needs to be soldered, and the progress will be updated after testing.

Problems discovered so far: Two less positioning holes need to be drilled, and two studs on the shell need to be cut off for use.

It is expected to take a while - -. I plan to change the main control in the future. There is a problem with the MCU part, but there is no problem with Youlian.

There is a problem with the CADENCE copper. After the ground is laid, the previously laid power copper is avoided.
After I have finished copper plating and selected avoidance, I have changed to the previous power supply copper plating avoidance. Does this copper plating need to have the same priority as pads?
