Hi, how did you connect your USB TTL adapter to the serial of the 2.x.x PCB as there are only 4 out of 8 pins? I guessed you used jumper cables, however what ports should I connect to each other? Best regards Jonas

Hi!

You only need 3.3V, GND, RX and TX from the serial adapter and put the ESP in bootloder mode by pushing and holding the button before plugging the USB adapter into you computer.

The button on the PCB or should there be a button on the adapter?

The button on the PCB ✌️

Pushing the button; powering; releasing the button; connecting to USB port? Is that correct? Thanks for your help!✌️
