The LilyPad Micro is a smaller version of the LilyPad LED. The LED is the same, but it is mounted vertically and is not paired with a current-limiting resistor. The result is a board that is approximately 3 × 9 mm.
Note: Without a resistor, it is possible to burn out the LEDs in the LilyPad Micro boards. Conductive thread tends to have high resistance which can help, so you'll want to make sure your stitches are long enough to bring the current down to the LED's operating specs. If you're controlling these with the LilyPad Main Board, you needn't worry; it has current limiting built in.
Note also that the picture does not show the white-LED boards. The white LEDs on these boards have a fluorescent yellow lens. Click the link above to the regular LilyPad LED board to see what the white LEDs actually look like in their Off state.
The LilyPad Micro LED boards typically come in a strip. You can use pliers to snap them apart.
LilyPad Overview LilyPad is a wearable e-textile technology developed by Leah Buechley. Each LilyPad is 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!
