Recently, a big guy at Station B made this. Unfortunately, it has not been open sourced.
I really like this one, so I also made one for everyone using ESP8266. The current open source
version is 1.0v 1.0, and there are no problems. You can rest assured to use the first design. This current was miscalculated and has two large capacitors.
The new version optimizes the power supply and the position of the buttons. The latest version has been printed. If there is no problem in the test, it will be uploaded.
I am a novice, please give me some advice.
