I tried to follow a few tutorials which led me to put :
/boot/config.txt file and
Cables wiring according to the amazon webpage :
Red +5V, Black GND, Green TXD, White RXD
I plugged my red cable on pin #4, black on pin #6, green on pin #8 and white on pin #10
Nothing appears on my puTTY window, and I become desperate.
If someone already faced the same problem or, at least, knows how to solve it, I'd be glad he helps me !
Please excuse my english, this isn't my first language.
Edit : The cable works fine on my Android Things Rpi3, so it's not coming from the cable
