About this item

The ELECROW Crowtail‑MP3 Player 2.0 is a compact audio playback module designed for integration with microcontrollers via the Crowtail ecosystem. It’s well suited for projects that need sound feedback, voice prompts, background music, alarms, or simple audio output without requiring a full audio system. It features an onboard micro‑SD card slot to store audio files (MP3, WAV, etc.), and a standard 3.5 mm audio jack for connecting headphones or an external speaker. Control is done via a UART/serial interface using predefined commands to play, pause, change tracks, shuffle, repeat, adjust volume, and more. It supports general file systems (FAT16, FAT32), making it easy to manage audio file storage. The audio output is of good quality thanks to a 24‑bit DAC, giving a decent dynamic range and signal‑to‑noise ratio, so the output sounds clean in many hobbyist or embedded applications. The module runs from 5V power, draws modest current, and includes Crowtail’s 4‑pin connector for VCC, GND, Data/Control lines, etc. It is compact in size (~40×20×11.8 mm), making it easy to fit into custom enclosures. Overall, it provides a simple, reliable way to add audio to your projects with little extra wiring or coding overhead.
