'644P + dual 12bit DAC + RTC (Sanguino Compatible)

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.

So similar in specs to the duino644:

but smaller...
and with the FTDI and VR on board...

Looks nice, are all of the extra pins broken out? Hang on, that's a dual row of pins isn't it...

Nice.

I am glad you liked it. Thanks.

The header is a 2x20 header. Almost all of the uC pins are brought
out plus the two DAC channels, the two RTC interrupt/squarewave pins.
Pins 35-40 enable the board to be powered from an external supply.
When the Li-ion board is used the NB2A is built with a 2x17 header
on the top and a 2x3 header on the bottom..
