update, we have lots of pins now but are low on regulators as they were backordered.

Some hardware changes:
switched to the low power LCD from newhaven.
Max draw is 40ma vs 80ma = significantly less heat created.
Draw on low setting is 27ma vs 40. mid setting is 34ma vs 60ma
450 ohm backlight resistor instead of 82 ohm resistor for appropriate v-drop.
larger electrolytic capacitor (470uf instead of 330uf).
