The JQ8900-16P is a compact voice playback module supporting MP3/WAV formats. It works with USB drives, TF cards, and SPI flash for audio storage. Supports multiple control modes: button, 1-wire, and 2-wire serial. Ideal for voice alerts, smart devices, and embedded automation systems.
Features:
- Supports MP3 and WAV audio decodingvia dedicated hardware (DSP).
- Compatible with FAT file systems.
- Multiple control options: 2-wire UART, 1-wire serial control, and physical buttons.
- Audio files can be read from USB drives, TF cards, and SPI Flash.
- Functions as a USB sound card, card reader, and supports HID control.
- SPI Flash emulates a USB drive, allowing direct voice file updates.
- Full media playback control: play, pause, stop, next/previous track, and track selection.
- Can insert specific tracks, temporarily pausing the current one and resuming it after.
- Supports Chinese and English path-based playbackand file insertion—no need to know file serial numbers.
- Cross-drive insertionis supported (e.g., play from SPI Flash during TF card playback).
- Track combination playbackfrom specified folders is supported using song names.
- 30-step volume controlfor precise sound adjustment.
