First look at JQ6500 modules

For some time, on different chinese webstores (for example Banggood) there is a module called JQ6500 for sale:

jq6500-001 jq6500-002

it’s often described as a voice sound module or as an MP3 player sound module.

Actually JQ6500 is the name of the main chip hosted on the module:

jq6500-003

The chip is manufactured by a Chinese company named JQ. A datasheet for the chip is also available, unfortunately only in Chinese (but Google Translate can help to understand what it contains).

On the other side of the PCB, the module houses two additional integrated circuits:

[checklist]

  • a 16Mbit flash memory (25L1606E)
  • a 3W audio amplifier (HXJ 8002)

[/checklist]

When you connect the module to your computer via USB, it is detected as a CDROM drive. If you browse the content of the CD, you can find the MusicDownload.exe application that allows to upload audio files in the flash memory:

jq6500-rec-007

The software is in Chinese but its use is very simple: by moving to the second tab you can select the MP3 files to be uploaded. If you now move back to the initial tab, you can start the upload process clicking on the only available button. In the video at the end of this post you can see how it works…

You can control the JQ6500 chip in different ways. The easiest one is using external buttons connected to pins K1-2-3-4-5:

jq6500-004

When you press a button, the chip plays the corresponding audio file. For example if you press the button connected to pin K1, the chip plays the audio file named 001.mp3.

The onboard amplifier (HXJ 8002) is a mono IC and its output is connected to pin SPK+ and SPK-. You can therefore connect to those pins a small speaker. If you want a stereo audio, you can instead use pins ADL_L (left channel) and ADC_R (right channel) and connect them to an external amplifier.

Conclusions

This module is an excellent and inexpensive solution to add audio to your projects. The use of an internal flash memory has the advantage of not requiring SD cards or other media to store your audio files; in contrast its capacity (16Mbit = 2MByte) makes it more suitable to reproduce sound effects / guide voices than to make a music player.

In the next articles I will show you how to interface the module with Arduino … meanwhile here is a video showing my first tests:

ciao, ho trovato per caso il tuo articolo cercando su Google informazioni su questo modulo. Ne ho un paio ma mi sembrano non funzionare bene. In sostanza non sono sicuro di riuscire a copiare i file sulla memoria. Ho seguito tutta la procedura (invero abbastanza semplice) ma da Arduino quando lancio il comando per verificare il numero di file caricati, mi riporta sempre 0. Li sto usando con un esp8266. Inoltre non ho capito se ricollegando il modulo al computer, tramite l’utility integrata dovrei vedere i file caricati in precedenza, perchè nel mio caso in effetti non vedo nulla.

ciao massimo, non riesci a rivedere i files memorizzati ma sicuramente Arduino deve darti il conteggio esatto. Nei prossimi giorni pubblicherò un esempio completo con Arduino, prova a vedere se ti funziona…

Ciao Luca,

ho visto che continui con gli esperimenti sul jq6500. Attendo con impazienza il tuo esempio con Arduino. Io ho provato vari sketch, compresi quelli “ufficiali” ma non riesco ad ottenere alcun suono.

Cari Saluti, Luca.

Ho fatto un nouvo versione dello rescue tool, piu facile da usare, 32Bit per ogni computer. Ho anche citato il tuo video su Github.

Tanti saluti a Berlino,

Nikolai – che parla solo un pocco italiano 🙂
