这是一个可以无损将任意外接电源改装成cr2032电池的适配器，比如aa或aaa电池，如果有条件还可以外接成usb供电。

This is an adapter that can non-destructively modify any external power source into a CR2032 battery, such as AA or AAA batteries, it can also be connected to USB for power supply.

准备 You will need

1. 总直径1.4mm左右的电线。

A wire with a total diameter of about 1.4mm.

2. aa/aaa电池和盒子 或 其他可以供电的设备（可以转换为3v的设备都可以）

AA/AAA batteries and Compartment or other power supply devices (any device that can be converted to 3V can be used)

操作指南 Instructions

接线示意图如下（背面视角），红色为正级，蓝色为负极

The wiring diagram is as follows (from the back), with red as the positive pole and blue as the negative pole

实物视角

注意事项

1. 需要一点耐心将电线慢慢插入对应的孔洞。如果发现插不进去，可以旋转电线。
2. 接线时最好将线的外壳推入一部分到孔洞内，可以起到固定作用，更加稳固。

3. 正极和负极都预留有收纳孔，故意留小了，你可以将线对折插入孔中，可以使接触部分根加牢固。

其他

配置文件中有两个模型，唯一的区别是第二盘带有正级电线固定槽，可以优化安装时正极接触部分偏移问题。

There are two models in the configuration file, the only difference is that the second disc has a positive wire fixing groove, which can optimize the problem of positive contact offset during installation.
