Topic: MP3 module on Ebay.. Does anyone know about this? (Read 1 time) previous topic - next topic


Hello fellow Forum users,

Currently I am working on a building a prop project and one day I decided to use a micro controller, Arduino, to add movements and cool sound effects.
So I've been searching everywhere on the internet and surely a lot of people have uploaded posts about sound module that they used with Arduino.
This week I found this MP3 module that seems like isn't China-made chip sells and plays only MP3 files.

MP3 module -> http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=380467927980&ssPageName=ADME:X:RTQ:US:1123
Datasheet -> http://mdfly.com/Download/Module/AU5121Sspec.pdf

To me it seems straightforward, and I don't think connecting it to Arduino won't be a pain. However, I have not seen people using this.
The seller has replied to my question that Arduino is capable of driving this module, so there wouldn't be any problem.

Can anyone provide any extra information about this module? Sorry if it's a stupid question.
Thank you for reading.


Seems very easy to use.
The only relevant reference I could find was this
which links to a this youtube video of a home made slot machine (cool project BTW)


I did see the module requires 6-12v.  I believe the Arduino only does 5v.  That may be enough but you may have to throw together a little amplifier to bump up the voltage a bit. 

Rx, Tx TTL level signals

That sounds perfect for talking to the Arduino.



Thank you for your kind answers.

I think using a separate battery for the audio module would be perfect, like 9V battery.
