Simply attach the ESP module to the burner through the test loop, and you can start downloading directly. There is an automatic download circuit.
The USB to serial port chip uses CH340, which is compatible with CH340G and CH340C (a crystal oscillator needs to be soldered when using CH340G)
To test the ring (directly search for "test ring" on Baobao), remove the ceramic beads, slightly open and straighten them, then cut them short, and weld the side of the test ring that is not completely straightened to the round hole on the board.
The four 1k resistors in the picture (pairs connected in parallel) can be replaced by two resistors of about 500Ω. (Since I didn’t have a suitable one on hand, I used two 1k resistors connected in parallel)
