Why go for such an arduino when the Uno and Nano are available?
First because it is much smaller, then because it also uses much less power (due to the missing FTDI chip).

The pro mini can be found here for about 6 € : .
The usb dongle can be found here for about 2 € : .

Below the wiring. As mentionned, since the usb dongle does not have a reset feature, press reset on the arduino right between the compiling and uploading part in the Arduino Gui.


In the Arduino Gui, dont forget to select the right card i.e « arduino pro or pro mini 5v / 16 mhz / atmega328).
