Description
The JQ6500-16P MP3 Audio Voice Module is an advanced standalone sound playback module designed to add high-quality voice, sound, or music playback to embedded and automation systems.
Equipped with the JQ6500-16P chipset, it integrates on-board 16 Mbit (2 MB) flash memory, a 24-bit DAC audio engine, and multiple control interfaces including UART serial and 5-key hardware trigger inputs.
The 16-pin layout provides speaker outputs, line-out pins, and power flexibility, making it suitable for both stand-alone and microcontroller-controlled operation.
Perfect for:
-
Embedded & IoT projects (STM32, ESP32, Arduino, Raayan Mini, etc.)
-
Smart automation, alarms, or voice notifications
-
Industrial systems requiring programmable audio feedback
-
Educational labs and student training on embedded audio systems

Usage Tips
-
Trigger Mode: Connect buttons to pins K1–K5 to play MP3 files (e.g., 001.mp3 → K1, 002.mp3 → K2).
-
Serial Mode: Connect TX/RX to your MCU UART (3.3 V/5 V) and use standard 0x7E command set for playback, volume, next/previous, etc.
-
Speaker Output: Use SPK+/SPK- for direct small speaker or DAC_L/DAC_R for external amplifier.
-
Use JQ6500 PC Uploader to copy MP3 files into flash (Windows utility).
-
Works perfectly with STM32, ESP32, AVR, or Raayan Mini boards in embedded audio projects.
