Circuit: buzzer, voltage sampling<\/p>\n\n\n\n

\"Laser<\/figure>\n\n\n\n

4 Instructions for Use<\/strong><\/p>\n\n\n\n

Burn the program, use it immediately upon power on, set it to save when powered off, and automatically load the last settings.<\/p>\n\n\n\n

When the main control chip is QFN packaged and soldered, please use a heating table \u2192 DC low-voltage heating table<\/p>\n\n\n\n

Pay attention to distinguishing components with positive and negative poles to avoid short circuits.<\/p>\n\n\n\n

Before powering on, please do not necessarily check for a short circuit to avoid chip burnout!!!<\/p>\n\n\n\n

Key functions (as shown in the figure below)<\/p>\n\n\n\n

5 Program related<\/strong><\/p>\n\n\n\n

    \n
  1. Prepare program burning (TTL connection PCB RX TX GND)<\/li>\n\n\n\n
  2. Press and hold the middle button to insert the USB, select the serial port, and click start (wait for the program to finish burning)<\/li>\n<\/ol>\n\n\n\n
