ABX00012 - Arduino MKR ZERO (I2S bus & SD for sound, music & digital audio data)
Arduino MKR ZERO (I2S bus & SD for sound, music & digital audio data)
The MKR ZERO brings you the power of a Zero in the smaller format established by the MKR form factor. The MKR ZERO board acts as a great educational tool for learning about 32-bit application development. It has an on-board SD connector with dedicated SPI interfaces (SPI1) that allows you to play with MUSIC files with no extra hardware! The board is powered by Atmels SAMD21 MCU, which features a 32-bit ARM Cortex(R) M0+ core.
Warning: Unlike most Arduino & Genuino boards, the MKRZero runs at 3.3 V. The maximum voltage that the I/O pins can tolerate is 3.3 V. Applying voltages higher than 3.3 V to any I/O pin could damage the board.
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.
