Hi all I'm trying to get this module working with my standalone breadboard arduino.
It's a cp2102 based breakout board and I already got it working with DUE without much trouble... I don't understand why it doesn't work on UNO. It's because it isn't 5v tolerant? (it's sold as arduino compatible!) so I tried with a jumper from tx to rx and it's still echoing (good thing... not burned). I tried SW serial and HW serial.
I don't care to use it to upload sketches. For now it is enough for me to just communicate.
Any clue?
TY!
