Note
When power is supplied, please check 5V and GND carefully. The circuit has no reverse connection protection, and the wrong connection may burn the chip.
When programming the program, IO0 and GND must be short-circuited, and the module needs to be powered on again. After programming, disconnect IO0 and GND and power on again to run the program normally.
