MKR ZERO brings you the power of Zero in a smaller form factor created by the MKR form factor. The MKR ZERO board serves as an excellent educational tool for learning about 32-bit application development. It features a built-in SD connector with special SPI interfaces (SPI1) that allow you to play MUSIC files without the need for additional hardware! The board is supported by Atmel's SAMD21 MCU, which has a 32-bit ARM Cortex® M0+ core.
Warning: Unlike most Arduino and Genuino boards, the MKRZero operates at 3.3V. The maximum voltage that the I/O pins can tolerate is 3.3V. Applying a voltage higher than 3.3V to any I/O pin can damage the board.
The board includes everything you need to support the microcontroller; simply connect it to a computer with a micro-USB cable or power it with a LiPo battery. Because there is a connection between the battery and the board's analog converter, you can also monitor the battery voltage.
You can find the board's warranty information here.
In the Getting Started section, you can find all the information you need to configure your board, use the Arduino Software (IDE) and get started with coding and electronics.
