In this project we'll build an MP3 Player based on the Feather M0 with a Music Maker wing. It plays a wide range of audio formats like such as MP3, AAC, Ogg Vorbis, WMA, MIDI, FLAC, WAV (PCM and ADPCM)! It also features a removable SD card for storage! Its portable and easy to power with the Feathers built in rechargeable circuit. The tiny size is perfect for installing inside small areas or as a wearable!
Check out the following guide below to get a better understanding of the Feather M0 pin outs.
If you don't have access to a 3D printer, you can send the files to a service or check with your local hackerspace/library.
