Description: A simple, very bright, 250mcd, white 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. They're even washable!

Note: A portion of this sale is given back to Dr. Leah Buechley for continued development and education of e-textiles.

Dimensions:

  • 5x11mm
  • Thin 0.8mm PCB

  • Can I order only the purple substrate and solder on my own LEDs? (I actually need to use IR LEDs)

  • I’d like to connect more than 1 of these LEDs to each LilyPad output pin. Any suggestions on how to connect 2 or three of these to an output with a reasonable brightness? I would never have more than 3 or 4 pins active at any given time.
    Thanks in advance, Fred

    • I doubt you’ll have any trouble putting several LEDs on each pin. They’ll be brighter or dimmer, depending how many pins are active at that moment.

      • My real question is then - series or parallel, and any additional resistors required? Thanks in advance.

        • Parallel from the pin, and no additional resistors if you’re using the LilyPad LEDs. If you use standard 5mm LEDs, you’ll want to add resistors! I don’t have a tutorial right now that shows more than one LED per pin (but I’ll take it as a suggestion!), but here’s one that shows the circuit using multiple pins. To add more LEDs to the same pin, just continue to connect the positives to the pin and the negatives to ground. https://learn.sparkfun.com/tutorials/protosnap-lilypad-development-simple-hookup-guide/raygun-preparation

  • Is it possible to power the LEDs without any of the other Lilypad equipment, straight from a 3V power supply?

    • You can definitely run these without a LilyPad. But note that the forward voltage on these white LEDs is 3.3V, so your power supply will need to be higher than that.

      White and blue LEDs have higher Vf than other colors, which makes it more difficult to run them off single coin cells (which start off able to light them up but will quickly drop below 3.3V). You could use two coin cells in series, or you can use other colors that have a lower Vf (red is the lowest at 2.0V, so will run the longest on a coin cell).

      I hope this helps, have fun!

    • Yes, I believe that the LEDs should work without any of the other Lilypad Equipment straight from a 3V power supply. I made a circuit with the LilyPad Coin Cell Battery Holder & Switch for a workshop and some of the LEDs. I did not have any problems with the 3V coin cell. So if you just power the LEDs straight with the 3V power supply you should not have any problems.

      One thing to note is that if you have multiple LEDs in parallel, there might be a limit on how many you can light because the current divides. The purple had problems lighting up with around 8 to 10 in parallel because we could not provide enough forward current required for each color LED.
