There appears to be solder directly connecting pins 91 and 92 (F.5 and F.6) on my 1280n dev board. I'd guess this not intentional; others don't have this, right?
Second, J.4 and J.5 are shorted together somewhere on the board, but I can't seem to trace where this occurs. Any thoughts or past experiences? |

That sounds like a solder bridge that was not detected. It can be removed with solder wick.

Perhaps it would be most expeditious for us to send you a new board. We can take a look at yours later. |

I wanted to verify that this was not intentional--eg. some Vref trick going on, etc. Since this isn't normal, I'll remove it.

Thank you for the offer. Since a new board would be fairly time consuming to alter to the current one's state, I'll just avoid using one of J.4 / 5, and in particular avoid setting both to output... |
