I bought three Nano boards from internet, very cheap, but not usable with IDE. The boards came with the blink sketch already programmed. Therefore I believed they are all ok. But I cannot upload any sketch. After some minutes there is a timeout. I could reload the bootloader via the ICSP pins, i.e. the controller seems to be ok. The Nano board contains no second ICSP for the USB to serial converter.
Has somebody experience with such a problem?
With an ICSP programmer the boards could be usable. I'd like to write my sketches with the IDE. What type of programmers do you recommend? Are there programmers supporting debugging?
