LilyPad Technology

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, but remove batteries.

Lilypad LED White (5pcs)


  • Simple very bright
  • 250mcd
  • White LED LilyPad.

Quantity : 5


Lilypad light sensor

With exposure to daylight, this sensor will output 5V. Covering the sensor with your hand, the sensor will output 0V. In a normal indoor lighting situation, the sensor will output from 1 to 2V.


  • 20mm outer diameter
  • Thin 0.8mm PCB
  • Light sensor that outputs an analog value from 0 to 5V.

Quantity: 1


Lilypad power supply

This board was designed to be as small and inconspicuous as possible. Pop in a AAA battery, flip the power switch, and you will have a 5V supply to power your LilyPad circuit.


  • 56x26mm
  • Thin 0.8mm PCB
  • Good up to 200mA. Short circuit protected.
  • This board has AAA battery clips but can use an input from 1.2V to 5V.
  • Our lithium polymer batteries are a good, rechargeable alternative.

Quantity : 1


LilyPad Temperature Sensor

The MCP9700 is a small thermistor type temperature sensor. Doing an analog to digital conversion on the signal line will allow you to establish the local ambient temperature. Detect physical touch based on body heat and ambient conditions with this small sensor.


  • 20mm outer diameter
  • Thin 0.8mm PCB
  • This sensor will output 0.5V at 0 degrees C, 0.75V at 25 C, and 10mV per degree C.

Quantity : 1


LilyPad Accelerometer ADXL335

This is a three axis accelerometer for the LilyPad system. Based on the ADXL335 MEMS accelerometer from Analog Devices, the LilyPad Accelerometer can detect joint movement as well as inclination and vibration.

The ADXL335 outputs a 0V to 3V analog signal on each of the X, Y, and Z axis. You will need to convert this analog voltage to a gravity amount and use trigonometry to calculate a true ‘angle’. If you are not looking for tilt, it is very easy to use this sensor for basic motion sensing.


  • 20mm outer diameter
  • Thin 0.8mm PCB

Quantity : 1


LilyPad Vibe Board

Apply 5V and be shaken by this small, but powerful vibration motor. Works great as an physical indicator without notifying anyone but the wearer. This version uses a surface mount motor which is less likely to be damaged during use.


  • 20mm outer diameter
  • Thin 0.8mm PCB

Quantity : 1


Arduino LilyPad USB – ATmega32U4

An updated version the Simple board to create the LilyPad USB by replacing the classic ATMega328 with the new ATMega32U4. Not only does that mean that it’s running a variation of the latest and greatest bootloader, but it also means no more FTDI Basic. The only extra piece of hardware you need to program the LilyPad USB is a micro-USB cable, since the new IC has built-in USB support. The LilyPad USB is also officially supported in the Arduino IDE as of version 1.0.2.

Just like the LilyPad Simple, this board features a JST socket so you can directly connect a Li-Po battery for power and an on-board power switch so you can turn it off when you’re not feeling particularly blinky. These boards were designed to streamline your next sewable project by keeping things simple and giving you more room to work while eliminating the need to sew a power supply. The LiPo battery is even rechargeable through the board, no more special external LiPo chargers are required.


  • 50mm outer diameter
  • Thin 0.8mm PCB

Muscle Wire


Muscle Wire 150um dia 1m 180-752

Muscle Wires are thin strands of a nickel tritium alloy called flexion – it is a type of shape memory. At room temperature the wire is easily stretched by a small force. When they are heated by an electric current they return they return to the pre-stretched size, contracting with a usable amount of force. Could be used for a light-weight actuators and power switches requiring low voltages that can be used in conjunction with control boxes.

An example of this includes the Basic Lever Arm. When you press the switch it lets the power through the muscle wire, heating it causing it to contact and raise the lever to lift the weight. When the power is removed the muscle wire cools and relaxes and the weight returns it to the starting position.


  • Flexinol wires contract by 3-5% irrespective of gauge size.
  • Flexinol wire is rated at >1,000,000 cycles when used as per manufacturer’s
  • Flexinol wires contract very rapidly – as fast as you can heat them.
    Wires relax more slowly – it is dependant on ambient cooling conditions.
  • Wires must be pulled back to their original, relaxed condition by external
    means eg. sping, gravity, rubber band.
