@dirkb19 Use Arduino 1.6.13 and not 1.8, it's a problem related to fuses with clones... You need to program with another arduino nano (or other) as ISP Then use the following: Duemilanove > 328P arduino as ISP plug the 7-19v Vin on the rboard You may also have to burn the bootloader And maybe need to press manually reset button on rboard, personally i don't need to. I've been struggling for a while with this board.
