XY-V17B Serial Control Voice Playback MP3 Player Module

XY-V17B Serial Control Voice Playback MP3 Player Module is an industrial embedded MP3 and WAV audio playback processor board equipped with 32M-bit (4MB) flash memory and a high-efficiency 5W Class D audio amplifier. Featuring selectable operating modes configured by hardware DIP/solder switches, it supports single-cycle, continuous, combinational, and UART serial control, allowing microcontrollers to play specific voice tracks with millisecond response times.

Key Features:

• High-Power 5W Audio Drive: Onboard Class D power amplifier delivers up to 5 Watts into a 2Ω/4Ω speaker.
• Integrated 4MB Flash Memory: Stores high-fidelity audio tracks without requiring external memory cards.
• USB Drag-and-Drop Updates: Mounts as a standard USB flash storage device when connected to a computer for audio loading.
• Multiple Trigger Modes: Configurable for UART serial control, 1-wire serial control, or direct button-triggered playback.
• Wide Working Voltage: Accommodates 3.3V to 5.5V DC supply rails with low quiescent standby power.
• Busy Status Output: Hardware output pin indicates when an audio track is actively playing.
