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/ADA1790:1.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 Bend all audio files to your will with the Adafruit Music Maker shield for Arduino! This powerful shield features the VS1053, an encoding/decoding (codec) chip that can decode a wide variety of audio formats such as MP3, AAC, Ogg Vorbis, WMA, MIDI, FLAC, WAV (PCM and ADPCM). It can also be used to record audio in both PCM (WAV) and compressed Ogg Vorbis. You can do all sorts of stuff with the audio as well such as adjusting bass, treble, and volume digitally. All this functionality is implemented in a light-weight SPI interface so that any Arduino can play audio from an SD card. There's also a special MIDI mode that you can boot the chip into that will read 'classic' 31250Kbaud MIDI data from an Arduino pin and act like a synth/drum machine - there are dozens of built-in drum and sample effects! But the chip is a pain to solder, and needs a lot of extras. That's why Adafruit spun up the best shield, perfect for use with any Arduino Uno, Leonardo or Mega. **This version of the shield only has stereo line/headphone output.** [We also have a version with a 3W/channel class-D stereo speaker amplifier for easy use in projects that need to be loud](https://core-electronics.com.au/adafruit-music-maker-mp3-shield-for-arduino-w-3w-stereo-amp-v1-0.html) Adafruit believe this is the best MP3 playing shield you can get, and at a great price too. Here are some specs: - Features the VS1053B codec chip - decodes Ogg Vorbis, MP3/MP2/MP1, MP4, AAC, WMA, FLAC, WAV/PCM, MIDI. Encodes Ogg or WAV/PCM - Stereo audio out with proper audio filter caps and ground reference so it can be safely connected directly to headphones, a stereo system or other powered speakers - 7 extra GPIO's that can be written or read through the Arduino Library for reading buttons or lighting LEDs - MicroSD card socket, for any FAT16/FAT32 formatted SD card from 64Mb or greater. - Full 3.3/5V level shifting for SD and MP3 chipsets - Works with Arduino Uno, Mega, or Leonardo - Built in MIDI synth/drum machine with dozens of instruments - Plenty of optional breakouts for pins like the card-detect and microphone input Each order comes with one fully-assembled and tested shield, 2 2-pin terminal blocks, a stick of 0.1" male header and 2x3 female header for the ICSP connection. Some light soldering is required to attach the through-hole headers to the PCB for plugging into the Arduino as well as the terminal blocks for the speakers. **Speakers, $1 headphones, SD card and Arduino not included!** [Adafruit have a detailed tutorial with lots of information about the VS1053 as well as instructions for how to use Adafruit's Arduino library that will get you playing sound effects in under 30 minutes](https://learn.adafruit.com/adafruit-music-maker-shield-vs1053-mp3-wav-wave-ogg-vorbis-player) ## Technical Details Revision history: - Sep 22, 2014: Adafruit updated the analog section to have more filtering, which should improve audio output quality (even more!) There are no wiring or code changes. Details: - Dimensions(assembled): 69mm x 53mm x 2mm / 2.7" x 2.1" x 0.8" - Weight: 14.7g - [Datasheets, EagleCAD PCB files, Fritzing object and more in the tutorial](https://learn.adafruit.com/adafruit-music-maker-shield-vs1053-mp3-wav-wave-ogg-vorbis-player/downloads) ![](https://core-electronics.com.au/attachments/localcontent/rohs_icon_8216055e11.jpg) ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/1/7/1790-00.jpg)
