Arduino MKR ZERO (I2S Bus & SD for Sound, Music & Digital Audio Data)

Arduino MKR ZERO

Arduino MKR ZERO is a popular educational development board which contains the ATMEL SAMD21 microcontroller. It is made to integrate the core's low power consumption and high performance. Learn about 32-bit application development. It allows you to play with music files and no additional hardware is required.

What can you find on Arduino MKR ZERO board?

• Onboard SD connector with SPI interface
• Additional I2C Port - which apart from SDA and SCL signals includes the GND and +5V power rails
• Onboard LED - connected to a dedicated pin (32)
• Vin pin - used to power the board with regulated 5V source
• 5V - it outputs from the board when powered from the USB connector or from the VIN pin of the board
• VCC pin - outputs 3.3V through on-board regulator
• LED ON - connected to the 5V input from either USB or VIN
• Charge LED - driven by the charger chip that monitors the current drawn by the Li-Po battery while charging

Features and Benefits

• 5V board power supply
• Li-Po single cell, 3.7V, 700mAh minimum battery
• DC Current for 3.3V/5V - 600 mA
• Circuit operating voltage of 3.3V - unlike any other Arduino board, this runs at 3.3V, therefore any higher voltage than that will damage the board
• 22 digital pins
• Flash memory of 256 KB and 8 KB for bootloader
• 32 KB SRAM
• Full speed USB device and embedded Host
