 The net effect is that we're making 12V from the gpio, which means all the LED
 current and switcher inefficiency is coming as current through that gpio.  The
-measured LED current is around 7mA, so this is "safe" for the SOC, but really
-not a great plan...

+Changing the circuit to be powered from v_lipo with the gpio hooked to shdn*
+and controlling a FET switch on the output might be smarter someday?

+- Seeed delivered v3.0 sans LCD, and we screwed up the orientation of the ALS,
+  so the work needed to prep a v3.0 for sale is:
+
+       - trim beeper lead excess (one is under LCD)
+       - reverse orientation of ALS
+       - install LCD
+       - install SMA
+       - flash / cal / test

-Need to redesign this in the future to use a transistor/FET switch.
