The LilyPad ATtiny85 Digispark Wearable Device is a tiny LilyPad board designed to be flashy yet functional without taking too much space. Small but smart as well, this board has a ATtiny mircroncontroller which you can sew 4 LEDs and connect a battery for blinky projects.
If you’re an advanced user and want to re-program the LilyTiny, the ICSP programming connectors are broken out on the back.
