As specified in the title, I try to connect my Rpi 3 running Raspbian Jessie Lite from 2017-07-05 to my Windows 10 PC using puTTY on serial mode with this cable.

I tried to follow a few tutorials which led me to put :


in my /boot/config.txt file and remove


from my /boot/cmdline.txt file.

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

Pin numbers according to this image enter image description here

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

    Forget whatever dodgy link you followed (which disabled BOTH Bluetooth AND serial) and enable serial from raspi-config. I STRONGLY suggest that you DO NOT connect the USB serial adapter 5V to the Pi 5V pins.

  • So I remove every edits I did and ONLY use raspi-config ?

You plugged the cables wrong. You have to plug RX to TX and TX to RX. Also plug ground to ground.

  • Thank you, I changed it, and used only raspi-config as @Milliways suggested and it works !
