Description: We designed this board to give the user a low profile button without any sharp edges. Button closes when you push it and opens when you release (momentary push button).

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:

  • 8x16mm
  • Thin 0.8mm PCB

Customer Comments

  • About how much pressure is required to close the circuit?

    • A fair amount. You would not be able to press it if, say, it was on a loose piece of fabric with nothing behind it and you couldn’t get any other resistance behind it. Akin to popping a piece of bubble wrap.

    • I wish that was in the description. I need that too

  • Is it washable?

    • We usually wash these surface mount buttons in a PCB washer using de-ionized water. It would be best to clean it with water that does not have minerals. Just make sure to dry the board and the switch as much as possible before before powering up the circuit.

    • I would recommend against it, just due to the type of button - but see the comment further down suggesting that you should be able to hand-wash this. It’s really not so much a problem of washing as it is of drying anyway :)

  • Do these require resistors to work like other buttons and switches? Sorry I’m an absolute newbie to Arduino in general.

    • If you are hooking this up to other LilyPad products, then no. If you are planning on using this in a different system than that, it will likely be dependent on your system specifically.

  • Where are the connection points?

    • The two crescent shapes on the edges, plus the plated holes, are the connection points :)
      The LilyPad line of products are primarily used for e-sewing, where conductive thread is wrapped through the hole several times making an electrical connection without the need for soldering.

  • so….. I mean how wet can this thing get? Its got metal parts so the button should cease to function and corrode if left out in the elements, right?

    • Yes, eventually this will stop working if left out in the elements for a long period of time. However, etextiles are designed so they can be hand washed if need. Of course, make sure you don’t have any current flowing through this when it’s wet. Electricity + water = fried components.

  • application for using it:
