The JQ6500 mp3 Voice Module is a compact, full-featured audio playback module designed to stream high-quality MP3 and WAV sound files directly in embedded microcontroller projects.
The JQ6500 mp3 Voice Module is a compact, full-featured audio playback module designed to stream high-quality MP3 and WAV sound files directly in embedded microcontroller projects. Built around the JQ6500 audio decoder IC, it features an onboard 16Mbit (2MB) SPI flash memory chip, eliminating the need for an external micro SD card for short sound clips, voice prompts, and alert tones. Equipped with an onboard 3W mono audio amplifier, this module can directly drive a small 8-ohm speaker without requiring external amplification circuitry. It supports dual control modes: standard UART serial control (for microcontrollers) and standalone key-trigger mode (using AD-key button inputs to trigger up to 5 individual audio tracks). Sound files are easily uploaded directly from a PC via its onboard Micro-USB port using built-in flashing software. This module is widely used in interactive voice prompting systems, elevator floor announcements, security alarm systems, smart home notifications, and custom audio toys. It is fully compatible with 3.3V and 5V microcontrollers including Arduino, ESP32, Raspberry Pi, PIC, AVR, breadboards, and custom printed circuit boards (PCBs).
