。 该开关可在nRF52832微控制器上运行。 使用带有印刷天线和用于外部天线MHF4的连接器的YJ-17103模块。 触摸开关由CR2430或CR2450电池供电。 传输模式下的功耗不超过8mA，睡眠模式下的功耗不超过6mA。
触摸开关板是在Diptrace程序中开发的，并考虑了根据Laser Iron Technology（LUT）的方法进行的后续制造。 开发的板尺寸为60x60mm（标准玻璃面板的尺寸为80x80mm）。 该电路印在杂志《天线》的页面上，并通过设置为“ Len”（最大功率）的博世熨斗转移到1.5mm，35μm的双面铝箔涂层玻璃纤维板上（如果没有另一个）。
用安装在DREMEL 220钻架上的DREMEL 3000微型钻头钻出用于层间过渡的孔，并用0.4 mm的钻头钻出用于层间过渡的孔，用1.1 mm的钻头钻出用于电池座的孔。 使用DREMEL 540喷嘴（切割轮d = 32.0mm），用相同的微型钻沿板边界进行修整。 播种在呼吸机中进行。
外壳和电池盖的最终模型以STL格式保存，然后有必要准备这些模型以在SLA打印机上进行打印（添加支架，方向）。 此时，由于家用SLA打印机的打印区域较小，因此出现了一个小问题。 相对于打印时间而言，处于最佳位置的设备机身模型不适合打印区域的大小。 当将模型放置在45度时，它的结果也令人失望，支撑重量等于案例模型的重量。 决定垂直打印模型，在正面之一上提供支撑，之前同意后处理的事实。 用50微米的层厚将外壳密封起来需要5个小时。 接下来，使用非常细的砂纸进行处理（我不会写这个数字，因为我不知道:)）。 电池盖打印了40分钟。
LED背光的漫射器是由带有3M 9088-200丙烯酸粘合剂的双面胶带制成的。 对于荧光灯，有多种材料可供选择，中国胶带和切成国内Luminophore公司胶带的胶带纸。 该选择是对国内制造商的青睐；根据我的感觉，它发光得更长，更亮。 将带有荧光颜料的纸制成的正方形粘贴在3M 9088-200双面胶带的顶部。
接下来是软件部分。 没问题 事实证明，TTP223传感器微电路在3.3V稳定电源下可完美工作，而直接由放电良好的电池供电时效果不佳。 在设备启动时，电源在2.5v范围内，加上在制作Mysensors演示文稿时出现额外的“下降”之后，TTP223芯片（在校准后立即）导致MK被中断，因为它带有活动触发器。
更改了向芯片供电的电路（带有gpio MK的电源管理TTP223），提供了额外的接地，在RGB引线（通过电容传感器板的另一侧）上，替换了具有更高电阻的电阻器。 它还已添加到软件中：启动Mysensors框架并编制演示文稿后，为电容性微电路激活电源。 通电后，TTP223芯片的自动校准延迟将加倍。 所有这些更改完全解决了此问题。
