1 Plan expectation

I have bought a lot of tubes one after another, and my technical reserves are almost there. It’s time to make a motion sensor of my own (error)!

As you can see, the motion sensor uses cnc金属外壳four digits 辉光管(tentative model), one on top 1/4w电阻, one in the middle 发光二极管, one on the bottom 1812电容, one big 陶瓷电容and one small 陶瓷电容(funny).

It can be expected that it is a two-layer board-on-board design, and the interface can be used 板对板连接器to SMD 1.27mmreduce the size as much as possible.

In addition, the CNC shell is 铆钉四颗连接外壳, according to the size of a normal palm, the PCB is expected to have a diameter of 48mm.

Already sent for proofing 2333. . .

The first version was marked with a package size, and then fine-tuned in EDA. Some 100mil holes were added to facilitate the assembly of components to match the original graphics of the motion sensor. However, the shell may not fit in, so some SMD components will be used. Encapsulate it (2333)
