KOOBOOK 2Pcs MP3 Voice Playback Module - SD/TF Card Trigger Player Board For Arduino Projects

About This Product

Electronics hobbyists and Arduino enthusiasts, these KOOBOOK voice playback modules are seriously cool for adding audio to your projects! Each board can trigger MP3 files from SD or TF cards, giving you multiple control options including I/O triggering and UART serial communication. The module supports various playback modes - you can have it play once and stop, loop continuously, play randomly, or respond to different trigger conditions. With support for up to 65535 files organized in folders, you've got plenty of capacity for sounds, voice prompts, music, or any audio your project needs. The boards work with 8 I/O pins for direct control or UART for more complex serial commands from your microcontroller. The file path formatting is specific but straightforward once you get the hang of it, allowing you to organize and trigger your audio files systematically. These are perfect for interactive displays, talking projects, alarm systems, educational tools, or any creation where you need reliable audio playback. The package includes 2 boards, so you can use one for development and one for your final project, or create multiple audio-enabled devices. The build quality is solid, and the functionality is impressive for the price. Whether you're building a talking robot, an interactive museum exhibit, a custom alarm system, or just want to experiment with audio in your electronics projects, these playback modules deliver professional-grade performance in a hobbyist-friendly package.
