Precautions

• Do not cut off the welding music enable pin header beyond the flat surface of the circuit board, otherwise it will hit the battery.
• The model is fixed on the board using iron wire (with corresponding openings). The iron wire can be removed from discarded disposable masks (I believe everyone has a mask)
• The program will be completed and uploaded later
• When making the board, try to use the one provided in my attachment. The PCB is imported from KICAD. I don’t know if there are any problems.
