#17178 I have this one

But its quite expensive. So. I'm looking for something cheap.
Variant like this

is great, but with micro USB connector it would be much better :-(

But it is very interesting, that my DTR pin stay LOW after flashing and module restart.
It is not problem until module will restart (after some error or power down), because it start again to bootloader mode.
I'm interested if all modules do the same.

It is not much simpler.
Actually it is a lot more complicated. Instead of two more wires and no additional work...
