New Duino644 kit (revision 1.1)

Thanks for ordering Duino644 kits.
At the moment, all of the "original", revision 1.0 (first batch of) PCBs are gone. In the meantime, I designed an improved version, by adding a few more components, to bring it closer to its intended functionality as the backbone of the Wise Clock:
  • 3 right angle push buttons (for setting up time, snooze, dimming etc);
  • piezo buzzer, for the alarm;
  • bright blue LED, as a background (and power indicator) light;
  • a bit bigger PCB.
This is the schematic for revision 1.1 of Duino644 (download Eagle file here):

and this is the board (download Eagle file here):

To my estimation, I should receive the new PCBs by Oct 20.
Once the new boards are in, I will have to re-price the Duino644 kit to cover the cost of the extra components, essentially increasing it by US$4, to a total of US$58 (free regular shipping to North America) and US$62 (free shipping outside North America) respectively.

The orders placed until then, at the old prices, will be filled with the new design. Consider this as a "promotion" campaign and take advantage of the "reduced" price.
