Description: The LilyMini ProtoSnap is a great way to get started learning about creating interactive e-textile circuits before you start sewing. Like other LilyPad ProtoSnap boards, the LilyMini ProtoSnap has all of its pieces wired together out of the box, enabling you to test the circuit’s function before you sew. At the center of the board is a pre-programmed LilyMini microcontroller connected to a LilyPad Light Sensor, LilyPad Button and two pairs of LilyPad LEDs.

The LilyMini ProtoSnap ships with pre-loaded code that uses all the LilyPad pieces connected to it. This sample code has three modes, which can be selected by pressing the LilyPad Button on the bottom-left side of the ProtoSnap. The built-in RGB LED on the LilyMini will change color to indicate which mode has been selected:

  • White: All LEDs on.
  • Magenta: LEDs fade in and out in a breathing pattern. When the light sensor is covered, LEDs fade faster.
  • Cyan: LEDs off. When the light sensor is covered, LEDs will twinkle.

The LilyMini board, at the center of the ProtoSnap, has a built-in battery holder for a CR2032 battery (included). The board can also be powered through the microUSB port while connected to a computer for reprogramming. On the opposite side of the LilyMini you will find the SAMD11 brain, which controls the ProtoSnap.

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

Note: The LilyPad LilyMini ProtoSnap does NOT include sewing needles or conductive thread. These items will need to purchased separately.

Customer Comments

  • I started a thread over in the forum (see forum) asking when the Arduino IDE support might be appearing (was tentatively 1/1/2017 - github).

    What’s the current ETA for Arduino IDE support?

    If not full Arduino IDE support, how about source code + build instructions for the example it currently ships with?



    • Hi Andrew, we’re working hard to bring LilyMini support to the Arduino IDE, and are currently targeting a June 1st release date. You can contact me (mike.grusin at if you’d like source code or other information. (We haven’t released source code yet because it doesn’t use standard Arduino constructs. We’ll release full Arduino source code with the IDE support.)

      • Hi Mike,

        Thanks for the reply and target release date. Best laid plans of mice and… ;-)


  • I’m typing this on Jan. 11, 2017, and they’re listed as “in stock”. I happened to notice the date on the schematic is 12/14/16. I’m impressed – I know the complexities of getting a new product out, though the schematic says “REV 10”, it still (likely) means a new PC board, and getting the manufacturing lined up. With all the holidays in there, less than a month is pretty good for a $15 product.

    • Credit where credit’s due: this board was a complex one for us, and development took longer than we hoped. This usually means that the last stage, production, unfairly shoulders the burden for getting it out on time. But even short-staffed for the holidays and with numerous high-priority builds on their plate, our production team quickly and flawlessly worked it into their flow. They’re the best in the business.

Great for teaching kids about circuits

I ordered several of these for our Maker group - It’s great for the kids to play with the functions before the incorporate them into a project. It really helps them understand how everything will need to be connected.

It's a toy, not a tool

Given that the other Lilypads have Arduino IDE support, and given that no where in the product description does it say the LiliMini does not, and given that it has a USB port (that’s a lot of givens), it is reasonable to assume that you can reprogram this board. You cannot. At least not easily, and only by soldering a connector on for an external programmer. Five months later and still nothing. The blinking LEDs are only entertaining for so long.

Sorry to hear about the issues with the Lilypad mini. We’re still working on getting the arduino definitions and programming method setup on the new SAMD11 board that’s on the Lily mini - it’s a little different from the traditional lilypads AVR chip. We hope to have them up as quickly as possible.

I apologize for any frustration that working with the board before the Arduino USB programming capabilities are finished.
