Got mixed reports, seems some v2.0/2.1 do and some don't, should be a quite simple check, just download the Arduino IDE (link on video) and if you get

"avrdude: stk500v2_ReceiveMessage(): timeout" error messages you have no bootloader.

(working on a video tutorial on adding the bootloader to printers, so would be really interested in hearing if your i3 v2 does or doesn't have one)

one thing you will need to do is add the Sanguino boards to the arduino IDE, really simple download

Go to where ever you have installed Arduino, go to the hardware folder and unzip the file into it.......the Sanguino boards should all now show up in Arduino IDE, and you will want the Sanguino ATmega1284p (16MHz) I belive.
