Ok, the thing is i don't have a credit card which i can use freely, which really hampers my ability to buy from the internet. Also, i live in southamerica, which makes makes it even harder to get some components.. Can't i get away without the usb connection? i have a serial port on my pc..
edit: i don't see any terminals on the back on the board, could it be that on the R3 UNO they moved them at the front of the board?
edit2: comparing my board with the one in http://arduino.cc/en/uploads/Hacking/Uno-front-DFU-reset.png (where the 10k resistor should be soldered on the back) i can check that the terminals i thought where the ones are also on this one. but i can see also that i have an extra resistor in that area. Could it be that the UNO R3 already has the resistor soldered in position?
