The size of it is so helpful, we’ve eliminated the resistor, changed the orientation of the surface mount, shrunk the board, and now it looks just perfect! No extra weight is exposed!
LilyPad is a wearable technology, it’s designed in a way that accepts having large connecting pads, this allows them to be sewn into clothing, they’re washable, and also many inputs, outputs, power, and sensor boards are available.
Note: Because the board doesn't include a current-limiting resistor, it is possible to over-power them and possibly burn them up. The high resistance of conductive thread can help protect the Micros from high current, so long stitches can be used with most power sources to keep the power levels 'Micro-friendly'. If you aren't sure where to start with resistance and current, using these in conjunction with a LilyPad Simple or Main Board is a great place to start, because they both have built-in current limiting and can't burn up your Micros.
Note: These are sold in strips of five boards which can be snapped apart with pliers. Some, however, may come as loose pieces that are already snapped apart.
