It contains three types of calipers. The first is the standard version, which is painted directly according to the calipers sold online. The size is basically the same. The second is the free version that is processed on the basic version. This version is mainly It covers most of the content and can be brought into the examination room. Some modifications may be needed. The third one is completely out of the scope of the caliper. It is a 4in1 NFC card. I will elaborate on it in detail and pay attention to all of these. The best thickness of the board is 1mm.

There's a point here. I'm not sure if the one I modified can be used because the lamp model I used is different. But I've also tried it. It can be done without attaching the lamp and just drying it with a piece of tin.

By the way, the blue plate is really nice.

I adapted the third one by referring to this author's PCB. I will explain it here. I also hope that more high-quality creators like this will appear.

Finally add a link, this is the GitHub repository of Rainforest Studio, you can take a look if you have nothing to do (the GitHub server is not a Tudou server, why doesn't it have its own server, because it is poor)
