Specifications

Key Features

• I2S Audio Bus: Dedicated Inter-IC Sound interface enables high-fidelity digital audio output to DACs, amplifiers, and speakers - perfect for music players and sound projects.
• Built-in Micro SD Card Slot: Read and write WAV files, log sensor data, or store configuration files without any external breakout boards.
• 32-Bit SAMD21 Processor: 48 MHz ARM Cortex-M0+ delivers significantly more processing power than 8-bit Arduino boards, ideal for real-time audio and complex algorithms.
• Li-Po Battery Ready: On-board JST connector and integrated charging circuit let you build truly portable, battery-powered projects right out of the box.
• Native USB: Appears as a serial/CDC device natively - no external USB-to-serial chip needed. Also supports HID (keyboard/mouse emulation).
• 10-Bit DAC Output: True analog output for generating audio waveforms, control voltages, or smooth signal outputs without PWM filtering.
• Compact MKR Form Factor: Breadboard-friendly 25 mm width with full compatibility across the MKR shield ecosystem (WiFi, GSM, ENV, Relay, etc.).
• 3.3 V Logic: Directly compatible with modern sensors, displays, and communication modules without level shifting.
