MKR Zero-board

MKR Zero

The Arduino MKR Zero is a development board for music makers! With an SD card holder and dedicated SPI interfaces (SPI1), you are able to play music files without extra hardware.

The MKR Zero board is a great board for getting started with various music projects. Using the popular Arm® Cortex®-M0 32-bit SAMD21 processor, it also comes with a micro SD card holder with dedicated SPI interfaces. The board is part of the MKR family, where you can choose from a large variety of shields to build projects out of the box with minimal effort!
Cortex-M0 32-bit SAMD21

The powerful, low-power processor that is used in all MKR Family boards.

Micro SD card holder

Store large media files, build advanced UIs for displays or log data offline: extra space is always useful.
