Arduino MKR ZERO Board

Description

A great educational tool for learning about 32-bit application development. It has an on-board SD connector with dedicated SPI interfaces (SPI1) that allow you to play with music files with no extra hardware! The board is powered by Atmel’s SAMD21 MCU, which features a 32-bit ARM® Cortex® M0+ core.

The board contains everything needed to support the microcontroller. Simply connect it to a computer with a micro-USB cable or power it by a LiPo battery. The battery voltage can also be monitored since a connection between the battery and the analog converter of the board exists.
