Precautions

The usage is the same as that of Aubao's development board. Install the CH34X driver and you can use it normally. Different 18650 battery boxes have different shrapnel strengths. For some battery boxes with harder shrapnel, it is recommended to use a flat-head 18650 battery charging chip ip5306 to dig holes at the bottom to facilitate welding with a soldering iron. If a heating plate is used, consider removing the hole pad under the ip5306. What are the problems in the project? Everyone is welcome to discuss in the comment area or private message.
