Arduino MKR Zero (I2S BUS & SD Included)

This is a revised version of Arduino Zero, aiming at assisting the learners looking to prove their 32-bit App development abilities. Arduino MKR Zero (I2S BUS & SD for Sound, Music & Digital Audio Data) features SPI1 interface which helps flirting with the audio/music without requiring an additional hardware. The best part of MKR Zero is the inclusion of SAMD21 (Atmel) Microcontroller. The ARM Cortex M0+ Core (32-bit) makes the board as powerful as the Arduino M0. If you love challenging your music-creation talent then consider Arduino MKR Zero (I2C BUS & SD) a top priority.
