LilyPad LED PCB Set

Replacement: None. There are no direct replacements for these boards but take a look at our LilyPad Protoboards. This page is for reference only.

These boards allow you to use your own 5mm LED as a LilyPad LED. If you've ever tried to 'spiral' the legs on an LED so that you can wrap conductive thread through the loop, you know why this board was created. When twisting, the legs on the LED can potentially break off. This board allows the user to solder in a through-hole device and then connect easily to conductive thread, forming a much more robust and sturdy connection. These boards work great to link anything through-hole (such as resistors, transistors, wires, connectors, etc) from soldered to conductive thread.

Each board has the correct holes to solder a standard 5mm LED (not included). These are packaged in packs of 10 boards, without LEDs.

The LilyPad LED PCB is a design concepted by Felicia Williams of Boulder, Colorado.

Note: Because of the 0.1" spacing for the LED, these can also be used to connect sensors, switches, etc.

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

  • felicia,
    I am looking to grab 64 or so of these in a whack for a project I am working on... and the power pack you are talking about will it fit in a tube... trying to find 5v to 12v that is lipo or some kind of rechargeable that will fit inside a 1/2 I.D. tube...

    • this is the power board that I was talking about.
      It has an on/off switch, lithium battery connection, and through-hole spot for a resistor. it's super tiny which makes it great for sequences of 5mm LEDS. I've used this set up with both wires and conductive thread, and it works great!

    • 1/2in tube is pretty small, but the electronics should all fit. Personally, I find that batteries are still really big and bulky, even the lithium rechargables. For a previous project that I worked on, I strung two lithiums together to get a 7.4V power supply. I needed the project to run for a few hours, so I used the 1000 mAh but I'm pretty sure they are more than 1/2in wide.
      I'm still talking to the sparkfun gods to see when more of these pcbs will be in and also where they are at with the simple power board. But, good luck with you're project! And let me know if you figure it out.

  • Cool! What's a PCD? Perhaps they mean pcb?

  • Where does the resistor go? The DEV-08735 has a resistor, so I assume someone would want to use one here, too. Or, am I missing something?

    • There is no resistor set up on these boards. I protyped these guys for a project I'm working on that needed super bright LEDS sewn in.
      A bunch of folks have just been twisting the legs on standard 5mm LEDs to get brighter lights on their projects. The problem with twisting the LED legs is that they tend to break at the stem and short your project. So this board allows you to solder LEDs onto sewable boards and not worry about breaking/shorting.
      As far as the resistor goes, there is a simple power board that I also developed that has an on/off switch, lithium battery connector, and a slot for a resistor. It's in the protyping phase, but it works perfect with these 5mm LED boards.
