JQ8900 audio board

[69-cat]

Good Day, I have worked with the DFPlayer for years on my Halloween project and now this board (JQ8900) was mentioned on a Halloween Forum and had to look into it but cant find any data sheets that show serial communication data in English. Has anyone worked with this board that can share this information?

I haven't heard of it before, but I found this:

HDSD JQ8900 16p MANUAL | PDF | Computer File | Input/Output

The document provides instructions for the JQ8900-16P audio module. It can support MP3/WAV playback from TF/USB and has various playback controls. It has multiple control modes including UART and button control. It supports updating voice content stored in SPI flash. The module is small in size...

This seems to be where you need to head -

https://www.jekyll-labs.com/2022/12/jq8900-16p-mp3-player.html

That has links to JQ8900 translations and also JQ8400 which appears to be the same protocol, and I also found this -

It appears to use a similar protocol as other modules do - header, payload plus checksum - though I haven't gone through other modules' datatasheets to see if the commands are the same.

I would guess it would be easy enough to control with a PICAXE using existing code. For example ""AA 06 00 B0", play next file, would seem to be as simple as -

SerOut JQ8900_PIN, JQ8900_BAUD, ( $AA, $60, $00, $B0 )
