README
README.mdUINIO-Keyboard 多功能输入模组
UINIO-Keyboard 是一款基于江苏沁恒 CH452 的 64 位键盘输入装置，采用两线制的 I²C 总线通信接口，并且外扩有日本阿尔卑斯阿尔派（ALPSALPINE） 的 3 枚 EC11 旋转编码器、以及 1 枚 RKJXV 模拟量碳膜摇杆，基本覆盖了嵌入式开发当中主流的实体输入方案。
设计概要
- 同时板载有 编码键盘、旋转编码器、模拟量摇杆 三种常用的输入外设；
- 添加了六枚
3mm直径的机械孔，便于使用铜柱或者螺丝进行固定和安装； - 键盘按键使用
3 × 4 × 2.5封装规格的四引脚贴片按键，这里可以购买日本阿尔卑斯阿尔派的SKRPACE010型，或者国产讯普精密的TS-1089S-02526型微动按键； - 碳膜摇杆如果购买不到日本阿尔卑斯阿尔派（ALPS Alpine）的原厂型号，那么可以平替为国产的 广东控银 JP13 型摇杆；
- 关于 64 位键盘的具体键位编码，以及参考驱动程序，可以查阅沁恒官方的《数码管驱动及键盘控制芯片 CH452 数据手册》；

Questions
How big is the UINIO Keyboard PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the UINIO Keyboard use?
112 parts, built around the CH452A and RKJXV1224005. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the UINIO Keyboard KiCad files?
From the uinika/UINIO-Keyboard repository on GitHub, at the commit this page was made from: the board is UINIO-Keyboard.kicad_pcb and its schematic UINIO-Keyboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the UINIO Keyboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask uinika before reusing the design.
