+These are tiny prototyping areas. One hole is connected to GND. The others are not connected to anything.

+Extra current limiting resistors for the Wi-Fi and Trigger LEDS. Add resistors here (and possibly remove R30/R31) to adjust
+LED brightness.

+Test point for the -2.5V rail. Do not draw current from this rail as it will adversely affect the performance
