- NHD-0420H1Z-FL-GBW-3V3-ND is the LCD module

2009.06.01
- keithp wants a compass ... HMC5843

2010.10.30
- v0.1 boards arrived

  issues:
  	- holes for the LCD leads are too small
		- for prototypes, workaround is remove pins from LCD module
		  and use wire-wrap wire to connect the 14 leads

	- footprint for U17 (audio amp) is too wide .. need narrower SOIC 8
		- for prototypes, existing footprint will work with careful
		  placement of the part and/or hand soldering after reflow

- loaded and reflowed two boards

	- some silkscreen work is in order .. U1/U2 refdes could be better
	  positioned .. spots on IC's marking pin 1 should be outside chip

	- tqfp footprint for tiny48 seems "largeish" .. not fatally, but 
	  leaves me questioning a bit

	- kapton paste mask worked, but was harder to use than stainless

- notes from initial turn on before I forget

	- the footprint for the AVR ICSP connector is mirror-imaged!

	- it's easy to crowbar the 3.3V rail by over-driving the audio amp.
	  can we run it from unregulated lipo instead?  Would be nice to do
	  that, then crank up the gain.

- if we move off speaker to an earphone jack, perhaps DK CP-3523SJCT-ND ?

- be nice if the cheaper version could fit in Mouser 546-1591XXATBU, which is
  the translucent blue Hammond 1591XXATBU

- the new 2x16 displays Keith plans to test might all best be installed using
  double sided foam tape, like DK 3M4008-ND, which is 1/8" thick and 1" wide.
