Original Arduino MKR Zero development board ABX00012 Music/Digital audio I2S/SD bus
The Arduino MKR ZERO is powered by Atmel’s SAMD21 MCU, which has a 32-bit ARMR CortexR M0+ core
MKR ZERO brings you the power of zero in a smaller format built in the MKR form factor The MKR ZERO board is an educational tool for learning 32-bit application development
Simply connect it to a computer using a micro-USB cable or power it through a lithium polymer battery. Since there is a connection between the analog converter of the battery and the circuit board, the battery voltage can also be monitored.
Product introduction
MKR ZERO brings you the power of zero in a smaller format built in the MKR form factor.
The MKR ZERO board is an educational tool for learning 32-bit application development. It has an onboard SD connector with a dedicated SPI interface (SPI1) that lets you play music files without additional hardware! The board is powered by Atmel’s SAMD21 MCU, which has a 32-bit ARMR Cortex⑧M0+ core.
The board contains the chips required to support a microcontroller; Simply connect it to a computer using a micro-USB cable or power it through a lithium polymer battery. Since there is a connection between the analog converter of the battery and the circuit board, the battery voltage can also be monitored.
Main features:
1. Small size
2. Number crunching ability
3. Low power consumption
4. Integrated battery management
5. USB host
6. Integrated SD management
7. Programmable SPI, I2C and UART
