“I’ve just to understand why passing by the UsbART it doesn’t do the same…”
To protect the PC, we add a Diode on the Rainbowduino, the 5v from UartSB cannot drive Rainbowduino well.
To program the Rainbowduino:
- select correct COM port in the Arduino IDE;
- select correct Board in the Arduino IDE(Arduino Duemilanove 168);
If you can program the Arduino On your 64bit Fedora Linux, yes Rainbowduino will work with it well.
