If It Still Doesn't Work...
There is, of course, always an outside chance that you have a bad component. We pre-program
and test every WiFi module, and the other parts are factory-direct so the likelihood that one of
them is bad is very small. Nevertheless, it is always possible that something may be wrong;
there may be a bridge on the PC board itself, etc. If you have gone through all of the
troubleshooting steps and the board still doesn't work, let us know at
support@eggtimerrocketry.com . A high-resolution picture (5 megapixel or better) of both
sides of your circuit board and a description of the problem would be very helpful...
