{"title":"LilyPad MP3","handle":"lilypad-mp3","url":"/products/lilypad-mp3","description":"The LilyPad MP3 Player is an all-in-one audio board combining an Arduino-compatible microcontroller, MP3 decoder, microSD card socket, and stereo amplifier. Part of the LilyPad e-textiles line, it's designed to add music and sound effects to fabric creations, wearables, and interactive projects.\n\nOut of the box, it plays specific audio files when any of its five trigger inputs are grounded. Add an optional RGB rotary encoder and load the included alternative firmware for track selection and volume control via a user interface. Powered by a 3.7V LiPo battery (with built-in charging circuit) or an external 3.5–6V source.\n\nKey Features\n\n\nMicrocontroller – ATmega 328p with Arduino bootloader (Pro 3.3V/8MHz)\n\nAudio Decoder – VS1053B (MP3, WAV, OGG, and more)\n\nAmplifier – TPA2016D2 stereo amplifier\n\nCharger – MCP73831 LiPo charger (500mA default, adjustable)\n\nHeadphone Jack – 3.5mm stereo output\n\nTrigger Inputs – 5 inputs (also usable as analog, serial, and I2C)\n\nPower – 3.7V LiPo (charging built-in) or 3.5–6V external\n\nProgramming – Via 5V FTDI Basic breakout using the Arduino IDE\n\nOptional – RGB rotary encoder header for UI control (not included)\n\n\nIdeal For\n\nE-textile and wearable audio projects\nInteractive costumes and installations\nSound-triggered exhibits and props\nPortable MP3 playback devices\n\n\nPackage Contents\n\n1× LilyPad MP3 Player Board\n\n\nResources\n\nUser's Guide\nGitHub Repository\nSchematic (PDF)\nVS1053B Datasheet (PDF)\nTPA2016D2 Datasheet (PDF)\n","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":12134,"title":"Default Title","sku":"SF-DEV-11013","price":110.95,"on_sale":false,"in_stock":true,"available_quantity":42,"option1":"Default Title"}]}
