AVR < 20 mA SD 3.3V Small ( LiPo
MKR ZERO has an on-board SD connector with
dedicated SPI interfaces (SPI1) that allows you to play
with MUSIC files with no extra hardware!
Watch out music makers, we’ve got some news for
you! We have released two libraries for your
enjoyment:

Arduino Sound library
(https://arduino.cc/en/Reference/ArduinoSound) – a
simple way to play and analyze audio data using
Arduino on SAM D21-based boards.
I2S library (https://arduino.cc/en/Reference/I2S) – to
use the I2S protocol on SAMD21-based boards. For
those who don’t know, I2S (Inter-IC Sound) is an
electrical serial bus interface standard for connecting
digital audio devices.
