Arduino Mkr Zero (I2s Bus & Sd For Sound, Music & Digital Audio Data)

I2S Bus & SD! The MKR Zero features an integrated SD slot with dedicated SPI interfaces (SPI1), allowing you to play around with music files without any additional hardware! For those who may not know, I2S (Inter-IC Sound) is an electrical serial bus interface standard for connecting digital audio devices.

Attention musicians: We have some news for you! We have released two libraries for you:

• Arduino Sound Library - a simple way to play and analyze audio data with Arduino on SAM D21-based boards.
• I2S Library - for using the I2S protocol on SAMD21-based boards.

Arduino MKR Zero
The MKR Zero offers you the power of an Arduino Zero in a smaller format defined by the MKR form factor. The MKR Zero board is a great teaching tool to learn more about developing 32-bit applications. It features an integrated SD slot with dedicated SPI interfaces (SPI1), allowing you to play with music files without any additional hardware! The board is powered by Atmel's SAMD21 MCU with a 32-bit ARM Cortex M0+ core.
