坑二 机械键盘

[shownb]

引用自 https://www.showdoc.cc/TuKeyboard?page_id=3846046570596123

选择尺寸

玩家首先根据自身需求选择偏好的键盘尺寸
有20%、40%、60%、80%、100%尺寸
如果您对键盘数字区有依赖，如财务人员，搞20%键盘
如果您偏爱小键盘，对尺寸、便携性有要求，搞40%或60%键盘
如果您偏爱大键盘，搞87%或100%键盘

选择配列

1. 40%键盘配列
   常规配列
   
   普朗克配列
   

2. 60%键盘配列
   POKER配列
   
   64非左移配列
   
   64左移配列
   

3. 80%键盘配列
   无门牙配列
   
   大门牙配列
   
   小门牙配列
   

pcb 基板 base

卫星轴 stabilizer

有pcb 卫星轴 pcb stabilizer
定位板卫星轴 plate stabilizer

选择轴体 switch

轴体对于一把键盘的手感起基础决定作用；
五脚轴相比三脚轴多两个塑料定位脚，使用五脚轴可以不使用定位板，使用三脚轴必须使用定位板;单一系列轴体包含一套不同颜色轴体，不同颜色轴体代表轴体不同手感，具体手感好坏因人而异；
黑轴 红轴 茶轴 青轴 等等

选择定位板 plate

定位板的作用：防止轴歪；
如果您上一环节中选用五脚轴，轴体本身有防歪功能，定位板可用可不用，手感有别；
如果您上一环节中选用三脚轴，则必须使用定位板；

选择键帽 keycap

键帽材质有abs pbt等 键上面的印刷的工艺有激光 二次升华等。

选择灯珠

我没兴趣

选择工具

烙铁和焊锡丝是装配键盘的必备工具，用于焊接轴体和灯珠；
吸锡器是可选工具，用于解焊轴体和灯珠；
镊子是辅助工具，用于测试PCB及夹持小零件使用；
强烈建议新手选购高品质焊锡丝；

BLE基础常用概念

• Central（中心设备）：负责扫描，发现广播的Peripheral，向Peripheral发起连接。比如Phone，Pad等等
• Peripheral（外设）：具备广播能力，能被Central发现和连接。比如心率计，手表 我们的esp32模拟成的键盘
• Service（服务)：表示Peripheral可以提供哪些服务，比如心率计Peripheral就具备Heart Rate Service，血糖计Peripheral就具备Glucose Service。一个Peripheral可以具备多个不同的Services。
• Characteristic：更加精细具体的服务单元，也是数据通讯的载体，Service包含Characteristic。比如Heart Rate Service有Heart Rate Control Point，Body Sensor Location，Heart Rate Measurement 3个Characteristic。通过读取Body Sensor Location的值，可以获取心率传感器的位置。心率值是通过Heart Rate Measurement 通知出来。控制心率器，向Heart Rate Control Point写数据。
• Characteristic Property：不同的Characteristic支持不同属性，有可读，可写，通知等属性,比如Heart Rate Control Point支持可写，Body Sensor Location支持可写，Heart Rate Measurement支持通知。
