Hello Renatopinto,

Sorry for delay.

This is classic TTL cable: https://www.ebay.fr/itm/400708482567

Plug TTL Cable on your PC and lets windows install driver. Go in Windows bar and in "Device Manager" and in "PORT & COM" you will see your cable and his PORT attributed.
After that you need to have software to manage result of signal (on terminal), for exemple on Windows you have: MobaXterm
Launch MobaXTerm -> Select Serial Port ->Select right COM port -> Speed 15600lpbs and RUN
Plug your TTL cable on controal board (TX, GND, RX) and turn on the board.

and all result will appear on your screen !

Best regards
