Extension light board 12 holes

Overview

Light board
expansion The light board can be used for mechanical keyboard expansion lights and other situations where expansion lights are needed.
The components are only 12 ws2812b 3528 reverse-stick lights 12 104 capacitors (optional) At most, add pin headers

Pin header positions, refer to the Hanwen PCB placement of Xiaobai Driving
The board has been verified and divided
into two versions: 1206 capacitors and 0603 capacitors
Capacitors can be omitted (verified)
Theoretically, it can be infinitely expanded
Example Use STM32F103CBT6 development board, Arduino sample program verification
Mechanical keyboard expansion has also been verified
