Pictures of the final design of my NB2A board are at Loading...
The NB2A has a 644P uC, a dual 12bit DAC and a DS1337 RTC with a battery
backup. I have tested this board with Arduino-0017+Sanguino tools.
There are a couple of example sketches on the site.
The datasheet with schematic, bom, assembly instructions and application hints should be released next week.
Also on the NB2 page is a prototyping board (NB2A-PB1) and
a screw terminal board (NB2A-TB1). The Li-ion charger will be
done next month.
All of the boards are sized for the "standard" Altoids tin.
