Dear all, i tell you my experience with this great and cheap module and at the end, one problem i am having.
I plays ad4 ok, converted from mp3 using somotool.
Memory card was difficult to get one working finally checked two 2gb microsd one generic, the other one, kingston. And one generic 128mb microsd also worked, all of them fat formated.
I needed to play 2 short voice sounds one after the other, but could not get it with only one module, there was a gap (about 1 second) between each sound. So i used 2 modules conected to arduino Uno in diferent pins.
Problem: I cant get the amplifier output to work, when i connect the amp out to the amplifier,after inserting a 0.01uF between module output and amplifier input, i get a static noise in high volume and the voice sounds in a very low volume over the static.
Do you know which could be the problem?
Could I use the speaker out as amplifier input? Or I would damage the amp input?
Thanks!!!!
