You can use a DLink or similar 5v power adapter (make sure it says 5v) - 2 amps higher is needed as the datasheet says 1.8amp current draw. A 5v adapter for an ipod usually will not work as they usually max out a 1amp, some at 500ma.
Just connect the grounds with your arduino ground (as usual with any external power).
You for sure need more current than the arduino can handle, while it may light up leds lightly .. it could strain your board. A simple solution for a one off is to find a 3amp 5v supply, such as for a dlink router/hub. Make SURE it says 5v and will usually say around 3amp, but all you really need is 1.8 amps full on (white).
Be sure to connect the grounds between your power supply and the arduino.
Due to being a 5v supply, you can power your arduino directly from the power supply using the vin and ground .. which will intrinsically make your grounds common :). I do this all the time. Be sure to check the output to assure 5.2v or less and it should be steady.
Hope that helps .. happy LEDing.

For arduino ...
* the link above ..
also others ...
... and ...
There is also working code on the FEZ forum, but site not responding right now.
These are great boards if the same as the ones I used to get on bliptronics site. The shield working with arduino, netduino and FEZ.
Thanks for picking up this design sparkfun.

Ah - The color red. You realize they called the color red before you did .. so you can't use red for anything. My god - there is so much red on this site - what copy cats you are.
If they change the name to sparcfun .. I'd sue em.
Thanks for all your great products Spark.

I just realized I posted the comment on the hook ups on this product but I used the 5V version. Not sure if there is any difference .. just a note.
What a great product. Being brand spanking new it took me a bit to figure out all the details on how to use this on a breadboard and a chip / crystal only.
This was a great start ...
1) To get started quick, just hookup the Vcc and Ground from the breakout to the breadboard and you can skip the regulator part of the tutorial.
2) Once you have the chip wired on as shown in the tutorial ... remove the pin 1 run connections and setup the pins as follows:
DTR -> through a .1 cap then to pin 1 on the chip
RX1 -> to the Tx on chip (pin 3)
TX1 -> to the Rx on chip (pin 2)
5V -> to power in on breadboard
CTS -> to ground on breadboard
GND -> to ground on breadboard
3) Now Arduino with the Duemilanove (328) setup should work.
Note: I had issues running 0016 but 0015 runs fine (xp and windows 7)
If I did anything stupid and/or am passing on stupid advice please correct me.

Page eight shows the pin-outs but here is a summary.
There are seven little pin outs on the ribbon. The one closest to the panel is + and all others are ground. You can light up any or all of the lights at once.
I took one apart. There are six small LEDs on the end closes to the pin outs. You could use these as very small inline 6 led arrays as well as using them as a panel. Looking at the full size side (before taking it apart), the pins light up the leds right to left.
Inside there seems to be a small polarized sheets, two Fresnel lenses and a diffusion panel in the mix (to help defuse).
Hope that helps people looking at this product.
No public wish lists :(
