Hive mind, I put together a gherkin board for ****s and giggles, and I now find one key doesn't work. With the cable on the right, it's the second key from the right, middle row.
I have a feeling it's some careless dremelling cutting through a trace, the problem is it's under the ProMicro which is of course soldered onto the board. I have ordered a 24 pin socket to help debug and fix the trace (if needed) however I have no idea how to take the ProMicro off without going doing more dremmelling. Any advices?
