Hi.
This is what I wanted to do.
First
I have a mini amplified speaker.
This image is for representation purpose only. It is a cheap chinese mini speaker. It has on off switch, old Nokia style round hole power input. 5v 350mA, and a cable 3.5mm stereo pin coming out of it.
That's all.
It does not have any in built mp3 playback ability.
It does not have any usb or SD card support.
Just plain amplified rechargeable speaker.
It has a built in generic lithium ion unlabeled battery. (can you guess what could be the output voltage of that battery? )
However the battery doesn't work any more. It now runs only through the external power source.
Second
I found this mp3 module
I haven't purchased it yet
http://s.aliexpress.com/iii6FrUB
It has a TF Card slot
It has the following solder points
Spk + Spk -
Bat + Gnd -
It needs 5 volts.
But it is advertised as mp3 module for Arduino.
I don't want to do anything with arduino.
I just want to be able to add this module into my mini amplified speaker.
So am I right in thinking
If I do these following steps
Open the speaker box
Parallelly connect the power supply of 5v with this module.
And connect the speaker solder points of the module with the stereo cable that the speaker is having.
I'll short the left and right speaker wires into a single point as it is a mono speaker and I don't see stereo support in the module.
I place a single mp3 song (for test purpose) in a TF Card and insert it in the slot.
Start the power supply
Will the song play?
Is this project that simple?
Or am I missing something.
As they say it is mp3 module meant for Arduino.
Am I missing something?
Your advise please.
