Internal short between LED+ and RST#
|Assignee:||Andrew Kohlsmith||% Done:|
I guess I didn’t do the DRC with all layers on and ignored Eagle’s “2 errors on hidden layers” warning.
The LED+ and RST# signals are shorted on layer 15 right at the LCD connector, and a via is too close to the LED+ trace on the same layer.

The fix is easier than I suspected.
1. cut the trace between P$8 and the via that is shorting RST# to LED+
2. Install 1k pulldown resistor between pin 14 (RST#) and 16 (GND) of J1
3. Do not populate pulldown resistor R3
