Arduino MKR Zero

The MKR Zero brings you the power of a Zero in the smaller format established by the MKR form factor. It has an I2S bus and an on-board SD connector with a dedicated SPI interface that allows you to play audio files. 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 can be charged via USB. The battery voltage can also be monitored since a connection between the battery and the analog converter of the board exists.
