SW-3b Display Problem – Not Fixed!


I thought that re-soldering the pins on the LCD display fixed the problem, and it seemed to be fixed for a while. However, after one POTA activation, the display problem returned. The display changes from random characters, to all dark , then no characters at all. Upon further investigation, I found that the 3.3V regulator chip was outputting 4.95V. This voltage not only runs the LCD display, but the processor chip as well. Stay tuned for more details.
