17-key mirror keyboard, the perfect choice for the left hand (CH552)

Overview

It is still the CH552G main control chip, with simple peripheral circuits. It uses ws2812b RGB light chip with IC.
Except for the buttons, which are different from the second generation Gai17, there is no difference in the wiring. It just simplifies the diode and eliminates the full-key rollover, but it still works. 6 keys are triggered at the same time, so the firmware is still universal and
