Looking to build the smallest, handiest, bread-board friendly Arduino-compatible? The Ardweeny fits on the back of the included ATmega328P, taking up no more valuable breadboard space than the microcontroller itself!
We love Arduino. Those Italians know how to design an excellent microcontroller platform and share it with the world. And Mr. Kimio Kosaka's "One-Chip-Arduino" project inspired us to develop the Ardweeny; the smallest Arduino you can solder yourself with through-hole components! And remember folks this is a kit so some assembly is required and batteries are not included :).
We've designed a backpack printed-circuit board the fits on top of an Atmel ATmega328P straddling it. Solder the pins to the microcontroller's legs, and you're ready to join the open-source hardware revolution!
Fit this little guy pretty much anywhere, just add 2.7V-5.5V for power and you are on your way. We do recommend hooking up a 3.3V or 5V voltage regulator for stable sensor readings but the choice is yours.
Note: Requires external USB-to-TTL FTDI-type cable or adapter, like the Solarbotics TTLyFTDI or we also have the SparkFun Simple FTDI Adapter (parts 50512 or 50510) available as well.
Also Note: This product now comes with the Arduino 1.0 optiboot bootloader programmed into it. When programming via the Arduino IDE please select "Arduino Uno" under the Tools -> "Board" category instead of "Arduino Duemilanove w/ ATmega328". This bootloader not only has faster upload speeds but is now backwards compatible with products that use a FTDI USB-TTL converter chip.
Interesting side-note: So we heard you liked to Arduino while you Arduino, so we put an... ok, nevermind. Did you know that you can mount your Ardweeny into the socket of a standard '328-based Arduino board, and use the board to program the Ardweeny? Yup, the crystal on the main board co-exists with the one on the Ardweeny well enough to let it happen! Handy for when you need to reburn a boot-loader, or you're short on FTDI adapters!
