Part of the Lilypad E-textiles line, this board can be used to give your fabric creations the gift of music, or any other sounds you can put on a micro-SD card. ## Pricing - **Price:** $92.20 (inc GST) — $83.82 AUD, exc GST - **Quantity discounts:** 5+ $81.30 (exc GST) · 25+ $79.63 (exc GST) · 100+ $76.27 (exc GST) ## Availability & dispatch - Available with a lead time — expect dispatch between Aug 17 and Aug 24. ## How to buy - **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=DEV-11013:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/DEV-11013:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description The LilyPad MP3 Player is your all-in-one audio solution, containing an Arduino-compatible microcontroller, MP3 (and many other formats) audio decoder chip, micro-SD card socket, and a stereo audio amplifier. Part of the Lilypad E-textiles line, this board can be used to give your fabric creations the gift of music, or any other sounds you can put on a micro-SD card. It can be powered by a 3.7V Lipo battery (charger built-in!), or an external 3.5-6V source. Off the shelf, it will play specific audio files when any of its five trigger inputs are grounded, or you can solder in an RGB rotary encoder (not included) and load new firmware (included in the link below) to add a user interface for track selection and volume control! The board is compatible with sketches written for the MP3 Player Shield. Our example code uses Bill Porter's MP3 Player library, which makes writing new code very easy. All you need to do is add a microSD card and some speakers, and you're ready to rock. **Note:** A portion of this sale is given back to Dr. Leah Buechley for continued development and education of e-textiles and also to Arduino LLC to help fund continued development of new tools and new IDE features. **Features:** - ATmega 328p microprocessor with Arduino bootloader (Pro 3.3V/8MHz) - VS1053B MP3 (and many other formats) decoder chip - TPA2016D2 stereo amplifier - MCP73831 3.7V Lipo charger (preset to 500mA, rate can be changed if desired) - Headphone jack - Five trigger inputs, also usable as analog, serial and I2C (“Wire”) connections - Load new firmware (or write your own) using the free Arduino IDE - 5V FTDI basic breakout for battery recharging and reprogramming - Header for optional RGB rotary encoder (not included, requires soldering) **Documents:** - [Schematic](https://core-electronics.com.au/attachments/localcontent/LilyPad-MP3-v15a_129060e235f.pdf) - [Eagle Files](https://core-electronics.com.au/attachments/localcontent/LilyPad-MP3-v15a_1469958c487.zip) - [Code/Examples](https://github.com/sparkfun/LilyPad_MP3_Player/tree/master/Arduino) - [User's Guide](https://learn.sparkfun.com/tutorials/getting-started-with-the-lilypad-mp3-player) - [Github](https://github.com/sparkfun/LilyPad_MP3_Player.git) - [Datasheet](https://core-electronics.com.au/attachments/localcontent/vs1053_71231a1de72.pdf) (VS1053B) - [Datasheet](https://core-electronics.com.au/attachments/localcontent/tpa2016d2_133078ca3c0.pdf) (TPA2016D2) - [Datasheet](https://core-electronics.com.au/attachments/localcontent/33244_SPCN_9511094584a.pdf) (MCP73831T) - [Product Video](https://sparkfun.com/videos#all/l5xYtrwR6Mk/107) ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/l/i/lilypad_mp3__dev-11013__01.jpg)
