What is JQ6500 MP3 Player Module & Its Working

The MP3 Player is a tiny & cheap module that generates a simplified output that is directly given to the speaker. This module can also be used as a standalone module including a battery, pushbuttons, and speaker. An MP3 player is one kind of digital audio player or DAP that can play MP3 digital audio files. This article discusses an overview of the JQ6500 MP3 Player Module and its working.


What is JQ6500 MP3 Player Module?

The JQ6500 mp3 module is a simple module that can play typical stereo or mono MP3 files. The controlling of this module can be done through buttons or a serial communication protocol. This kind of module works through two dissimilar modes to activate it like serial communication & AD button control.

In the first mode, the module is connected to a microcontroller whereas, in the second mode, the module is controlled through switches. JQ6500 MP3 Player module is available in two models like JQ6500-28p & JQ6500-16p.

The JQ6500 28P model includes onboard memory and also includes additionally a slot of Micro SD card. This slot is very helpful to upload your MP3 files into Micro SD, use an OS except for Windows because you simply require a standard Micro SD card formatted with FAT. This is the best option if you need to make a music player.

JQ650016P mp3 modules include an onboard 2 MegaByte or 16Mbit Flash memory. Using Windows software into the device & come into view once you fix it to USB & MP3 files can be uploaded directly to your device. If you require fewer bitrate MP3s, then this is the best option.

These modules are available in two versions, the pinout & functionality are similar, the only difference is that the original one like V2.1 includes a Micro-USB in place of a small USB connector.


Alternatives ICs for the JQ6500 MP3 player module include WT588D-16P, VS1053, SparkFun MP3 Player Shield, MP3-TF-16P & Lilypad.

JQ6500 MP3 Player Module Pin Configuration

The pin configuration of the JQ6500 MP3 Player includes the following, This module has 16 pins where each pin & its functionality is described below.

  • ADC_L Pin is Amplifier or Headphones (Left Channel)
  • SPK- pin is a negative terminal of the speaker
  • SPK+ pin is a positive terminal of the speaker

Features of JQ6500 Module

The features of JQ6500 include the following.

  • The sampling rate supported by JQ6500 is like 8 KHz / 11.025 KHz / 12 KHz /16 KHz / 22.05 KHz / 24/32 KHz / 44.1 KHz / 48 KHz
  • Output is 24-bit DAC, the support of dynamic range is 90dB & SNR is 85dB
  • Operates in three control modes like parallel port, serial port, & AD button
  • It supports FAT16 & FAT32 file systems, where the major supports are 32G TF card, 32G U disk, 64M bytes of NOR FLASH
  • To play the particular music, it can be controlled by the serial port of the microcontroller
  • The sorting of audio data can be done through the folder, equal to 100 folders, where each folder can be allocated with hundreds of songs
  • Adjustable with 30 level & 10 EQ

Specifications

The specifications of JQ6500 include the following.

  • It supports all types of bit rates like 11172-3 & ISO13813-3 sampling rate with audio decoding.
  • It supports different sound effects like Jazz, Normal, Classic, Rock, Pop, etc
  • Humidity ranges from 5% to 95%
  • UART Interface: TTL level, Standard serial port, baud rate can be set
  • Operating temperature ranges from -40℃ to 70℃
  • Input voltage: Power supply ranges from 3.2V to 5V, but power supply like 4.2V is the best
  • Normal DIP16 package
  • The Rated current is 20ma

Control Methods

The mp3 module can be controlled in five methods, based on the particular application; the suitable method can be selected.

  • Using push buttons, manual controlling can be done toward the ground like the K*, PL/PAUSE, NXT/PRV, SRC pins
  • Manual control with the help of resistors and buttons toward the signal the action requested is throughout the ADKEY pin
  • Limited control through Infrared remote and the device can recognize using remote control codes, mostly to play the five hot-key files
  • Complete controlling can be done through an Arduino Library for the module. So this will give you control through some additional features like looping options, equalizer modes, direct access to several files over the SD Card, names of songs, etc.
  • The complete controlling can be possible through a protocol like serial communication on TX/RX

Circuit Diagram

The circuit diagram of the JQ6500 MP3 player is shown below. This circuit is frequently called an MP3 player sound module or voice sound module. The name of the chip hosted on the module is JQ6500.

The manufacturing of this chip can be done through a JQ company in China. On the other face of the printed circuit board, the module includes two extra integrated circuits like a 25L1606E (a flash memory with 16Mbit & HXJ 8002 & an audio amplifier with 3W.

Once this module is connected to the computer through USB then it is noticed like a CDROM drive. While browsing content for the CD, we can discover the application for MusicDownload.exe. This application mainly permits to upload of audio files within the flash memory

The controlling of the JQ6500 chip can be done in several ways but the simplest one is through outside buttons which are connected toward pins K1 to K5

Once you push a button from K1 to K5, then the module plays the equivalent audio file. For instance, if you push the connected button to the K1 pin, the module plays the 001.mp3 audio file.

The onboard amplifier like HXJ 8002 is a mono chip & its output can be allied to both the pins like SPK+ & SPK-. Thus, these pins can be connected to a speaker. If you need stereo audio, then you can use pins like ADC_R & ADL_L & connect them to an exterior amplifier.

So finally this mp3 module is an inexpensive & outstanding solution to include audio in your security-based projects. The internal flash memory is very useful because there is no requirement for SD cards to store different audio files.

Applications of JQ6500 MP3 Player Module

The applications of the JQ6500 MP3 player include the following.

  • Navigation of car broadcasted with voice
  • Inspection of Road transport, voice prompts at toll gates
  • Voice prompts with a security check at the bus station and train station.
  • Communications, Power, financial Business
  • Voice prompts for Border channel check
  • Fire Alarm
  • Automatic broadcast devices
  • Automatic alarms when electrical and mechanical equipment breakdown

Thus, this is all about an overview of the JQ6500 mp3 player module. This kind of module is very simple to use and it can be controlled manually using control keys otherwise serial protocol on a typical UART serial interface. Using easy serial commands, the playing of music can be executed. This module is very simple to use due to some features like reliability, stability, etc. This IC is customized uniquely like an economical solution for the precise voice playing field. Here is a question for you, what are the different types of music player ICs available?
