Thanks that totally worked

But FIRST:
Read the first post(s) of the "serial port" thread - - -
Read the links of that post to ways to make the connections without using hot solder.
You evidently do not have the tools needed to make hot solder connections.

Yes i'm aware lacking tools and skills for this (super tiny!) unfortunately i couldn't find any other way to make it stick, this time on the other side i was much more careful and i guess my skills have improved a bit since i also did other soldering in the last 24h so this one was done without any damage, obviously not professional \ missing tools so it's a bad solder joint but it holds well and i checked the voltages at some point i got 1.7 out of both connectors at other points it's 0 or something else like only one is 1.7 and the other i 0.
I still can't get anything to work tho and i'm getting very strange reading of voltage
on linux i get 0.9 on Rx and 3.0 on Tx while on windows i get 2.1 and 3.1 on the same and like i mentioned before sometimes i get them as 0.3 and 2.4
Also on Linux i can see the adapters detected as usb devices but i never get a ttyUSB device. the only tty device i get from dmsg is ttyS0 still missing the other one and the device to make it work (not sure if i'ts a driver issue), on windows i can see the adapters on the device manger but i get nothing on putty.
i was following this guide

and for linux

i tried 2 different adapters
This one is the one recommended

i got it set up with the 3v jumper

i doesn't have a direct usb connector so i'm using an additional cable for this but i can't get it to even recognize Rx or Tx and i tried GND from both sides
The other one i had is this one
https://ibb.co/5xPkt0t
https://ibb.co/7Rkq4Vc
It does have a direct USB connection but i never get a led on for TX just RX and GND
although there's voltage in Tx
This is how i have it setup\hooked

I also tried to add the battery although my reading suggested it's not needed as long as there a micro usb cable giving voltage to the board

BTW couldn't find the "serial port" thread not sure which one you meant
