Buy Duino644 kit

Updated Sep 30, 2011 - DISCONTINUED
This kit is no longer offered. It was replaced by the Wise Clock 3 kit.


Updated Jan 27, 2011

A redesigned (revision 2.1) Duino644 is back in stock. Read more about it here.

Note: Although I added a few more components and I made the board a bit larger, I decided to keep the price unchanged. I hope this is appreciated :)

Also, the picture below won't accurately reflect the actual component set. Missing are the 4 right-angle push buttons (one is replacing the reset button), the micro-speaker and the high brightness blue LED.

I have a few Duino644 kits for sale, on hand and ready to ship. After they are gone, any order will be fulfilled in about 4 weeks time.
Duino644 kits are US$54, with free regular shipping to North America.

For only US$10 more, buy the 2416 LED matrix display from Sure Electronics (ebay), and you can have a nice gadget on your desk to impress your friends an colleagues.

The Duino644 kit includes the following parts:

• PCB;
