Arduino MKR ZERO (I2S bus SD for sound, music digital audio data)
The Arduino MKR Zero brings 32-bit power to the compact MKR form factor, with the standout feature of an onboard SD card connector with dedicated SPI interface for playing music and audio files directly — no extra hardware needed. It also supports the I2S (Inter-IC Sound) bus for connecting digital audio devices.
Powered by the Atmel SAMD21 (32-bit ARM Cortex-M0+), the board can be powered via micro USB or a LiPo battery with built-in battery voltage monitoring through the onboard ADC.
Key Features
- Microcontroller – Atmel SAMD21 (32-bit ARM Cortex-M0+)
- SD Card Slot – Onboard with dedicated SPI1 interface
- I2S Bus – For digital audio device connections
- Operating Voltage – 3.3V
- Power – Micro USB or LiPo battery (with voltage monitoring)
