Sewable MCU Board for E-Textile Applications

SparkFun’s DEV-14631 LilyPad USB Plus is a sewable electronics microcontroller board controlled by an ATmega32U4 with the Arduino bootloader. It is a piece of wearable e-textile technology that is designed to have large connecting pads that can be sewn into clothing. This board comes with a built-in power supply JST and an On/Off switch, as well as an RGB LED, 6 white LEDs, and 14 sew tabs. The RGB LED is located at the center of the board with six white LEDs to act as a bar graph. The sew tabs are used for connecting components with conductive thread, four of which are reserved for connecting power, a ground of LilyPad sensors, accessory boards, while the remaining 10 tabs are used for I/O.
