LilyPad LED Purple (5pcs)
A simple purple LED LilyPad. Light up the night!
LilyPad is a wearable e-textile technology developed by Leah Buechley and cooperatively designed by Leah and SparkFun. Each LilyPad was creatively designed to have large connecting pads to allow them to be sewn into clothing. Various input, output, power, and sensor boards are available.
Note: The purple LED has a much higher voltage drop than other LilyPad LEDs so it will be dimmer than the others. What's voltage drop? Click here and get your learn on!
Note: A portion of this sale is given back to Dr. Leah Buechley for continued development and education of e-textiles.

A quick tutorial to get you started in the world of light up origami flowers.
Core Skill: DIY
Whether it's for assembling a kit, hacking an enclosure, or creating your own parts; the DIY skill is all about knowing how to use tools and the techniques associated with them.
Skill Level: Noob - Basic assembly is required. You may need to provide your own basic tools like a screwdriver, hammer or scissors. Power tools or custom parts are not required. Instructions will be included and easy to follow. Sewing may be required, but only with included patterns.

Core Skill: Electrical Prototyping
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Gah!!!just received my order with all my lilypad stuff!! Must...resist....buying.....
Wish I'd seen the note sooner: "The purple LED has a much higher voltage drop than other LilyPad LEDs so it will be dimmer than the others."
It's SO much dimmer than the others that I thought it wasn't working at all when I was working on a 5-color project, and only after troubleshooting did I realize that it had been on the whole time, and I just couldn't see it. I will plan my future projects accordingly, and I am unlikely to buy the purple lights again; they're just not worth it given how dim they are.
They are too dim for daylight use.
HOOKED UP THESE LEDS WITH LILLY PAD TWINKLE, THE LEDS ARE SO DIM YOU CAN HARDLY TELL THEY ARE WORKING. IS THIS THE WAY THE LILLY PAD IS PROGRAMMED? THE BATTERY IS 2.97V.
Purple and pink LED's are typically half the brightness of typical colored LED's made in the same style to the same electrical specifications.
They're a bit less bright, but I wouldn't say that they're 'dim' by nature.
However, at 2.97V for the battery.. making the assumption that this is what would go to these boards, and then assuming that the LED is at the lower end of the datasheet's Vf spec - 2.8V - then the 100Ohm resistor on this board means the LED's only going to be seeing a few mA. I would definitely expect it to be very, very dim. I'd guess these are supposed to be used with ~5V on the line.
I hope we get a micro version of this soon!
why would you solder headers like that and not just use 4 extra wires?
