I've assembled 3 units and I'm having an issue with one of them. I connected a PICIT2 to the good ones and they look fine. WHen I connect the 'bad board' to the PICKIT I get an "Unable to establish a valid Vdd on the target (Attempted 3.5V - Read 0V).
When I pop the PIC out of the 'bad board' and put it in a good one, I get a good PICKIT response from the good board. That tells me the chip itself is okay and that there is something going on with my board. I've re-flowed all the connections and I'm at a loss what could be happening. Any help would be appreciated. Is there a schmeatic for the new Rx/TX boards anywhere that I can use to troubleshoot? Any suggestions on what might be wrong?
Thanks
