ESP-01 CH340G Programmer

This programming adapter is equipped with a CH340G chip that allows USB to serial communication. The programming adapter is perfect for programming the ESP-01. Unfortunately, the ESP-01 is not automatically put into flash/programming mode. To put the ESP-01 into this mode, GND must be connected to the GPIO0 when plugging in. This is easiest if you insert a wire or < 1kOhm resistor on GND and GPIO0 on the adapter, the ESP-01 can then be plugged in. As soon as the programming adapter is now plugged into the USB port, the ESP-01 is in programming mode and can receive programs from the Arduino software. If you want to copy a program again later, the adapter always needs to be unplugged and plugged in again.
