Description

Official Arduino MKR Zero Development Board
The Official Arduino MKR Zero Development Board combines the powerful features of the Arduino Zero with the compact and versatile MKR form factor, making it ideal for creative and educational projects alike.
Designed around Atmel’s SAMD21 microcontroller, it features a 32-bit ARM Cortex M0+ core that enables efficient and robust 32-bit application development. This Arduino board is especially useful as a learning tool for developers exploring the world of modern embedded systems.
One of its standout features is the onboard SD card connector with a dedicated SPI1 interface, allowing users to play and manage music files without the need for additional hardware.
The MKR Zero development board is powered via micro-USB or a LiPo battery, offering flexibility in power management, and includes a built-in battery monitoring feature through an analog connection, adding further convenience for portable projects.
NOTE: Unlike most Arduino and Genuino boards, the MKRZero operates at 3.3V. The highest voltage that the I/O pins can withstand is 3.3V. Applying voltages greater than 3.3V to any I/O pin may destroy the board.
