{"title":"LilyTiny","handle":"lilytiny","url":"/products/lilytiny","description":"The LilyTiny is a compact LilyPad board with a built-in ATtiny85 microcontroller that drives four pre-programmed LED patterns. Simply sew on four LEDs and connect a battery — no programming or main board required.\n\nEach of the four output pads produces a different lighting effect: heartbeat pulse (pad 1), on/off blink (pad 2), breathing fade (pad 0), and random fade (pad 3). Advanced users can reprogram the ATtiny85 via the ICSP pads on the back of the board.\n\nKey Features\n\n\nATtiny85 Microcontroller – Pre-programmed with four LED patterns\n\nNo Programming Required – Connect LEDs and a battery to get started\n\nSewable Pads – Large conductive pads designed for sewing into textiles\n\nReprogrammable – ICSP pads on the back for custom firmware\n\nUltra Compact – 20 mm diameter, 0.8 mm thin PCB\n\n\nLED Patterns\n\n\nPad 0 – Breathing fade\n\nPad 1 – Heartbeat pulse\n\nPad 2 – On/off blink\n\nPad 3 – Random fade\n\n\nSpecifications\n\n\nMicrocontroller – ATtiny85\n\nDiameter – 20 mm\n\nPCB Thickness – 0.8 mm\n\nOutput Pads – 4\n\n\nIdeal For\n\nWearable e-textile projects\nLight-up clothing and costumes\nBeginner-friendly LED crafts\nE-textile education\n\n\nPackage Contents\n\n1× LilyTiny board\n\n\nResources\n\nSchematic (PDF)\nEagle Files\nReprogramming Guide\nArduino Source Code\nGitHub Repository\n","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":12294,"title":"Default Title","sku":"SF-DEV-10899","price":13.64,"on_sale":false,"in_stock":true,"available_quantity":127,"option1":"Default Title"}]}
