I have interfaced wtv020m01 module with arduino.
Pin1-pin 2 0f arduino
pin4-speaker+
pin5-speaker-
pin7-pin 3 0f arduino
Pin9-pin 4 0f arduino
Pin15-pin 5 0f arduino
Pin16-3.3v
pin8-gnd
I have used 30watt, 4 ohm speaker.
I used program which is given in examples of wtv020m01 library.
I used ad4 format.
Even i don't get output voice.
pls help..
The arduino is 5V. Although you have powered it from 3.3V, are the interface pins capable of interfacing with 5V?
On the module I just received from fleabay, there was a missing solder jumper to activate the 3.3V side. It's on the top of the module, near the notch on the pcb and will be hidden if you have a SD card inserted. http://electromicro.ru/images/cms/data/external_plate/mp3_web1.jpeg
I simply added a little solder to connect the center trace with the 3.3V trace, and it started working. Hope this helps!
what code did you use?
