If you store in SD card,the module only can support 16Kbps~320Kbps bit rate and 8KHz~44.1KHz sample rate MP3 and WAV file.

Don't Arduino nano have a 3.3v output?
yes but .. "when running on external (non-USB) power, the 3.3V output (which is supplied by the FTDI chip) is not available"
http://arduino.cc/en/Main/ArduinoBoardNano

so i think i will try to change the solder to the 5volts pin as suggested by Johnwasser (thank you)

Pls don't use 5 V ,it will destory our module directly ,maybe when you use for a while.the main chip of WTV020-SD module maximum voltage is 3.6V,so work voltage can not beyond 3.6V.

Of course the datasheets and info I have found are such horrible english that maybe it does support that somehow and it isn't clear.

I think I will order one as well. Would be nice to make a library for it, anyway.
:smiley-sweat:We will do english manual better in future

I've been working with a Somo-14D recently on a lightsaber project.  I got it generally working until I realized that it couldn't do gapless playback.  The gap was very small, but very noticeable when going from a swing directly into a hum.

Do you know if this module can do gapless playback?  I know the two units are similar, I just don't know how similar.

Thanks!

yes,it is same.it use same main control chip( WTV020 chip) and same program.

about gapless playback,WTV020-SD 16P can not do that,SD card response need some time,and main control can not do so fast communicate with SD card.

How long does your sound,maybe you can try SPI flash solution,it will response faster than SD card.

Hello!
I have a question!
How to manually change modes on vtv020-sd-16p,all ekys are on/off(loop),key 5 group of voice...
Thanks!!!

I want to ask which control mode module do you use?for example ,If you buy 2-wire series mode can not us key 5 group of voice,control mode is fixed when we program main chip,and you need tell supplier what you want,i think they will give you correct control mode module.

I  just got from China a board : V1.5 / 2012.01.12", and "5v  / 3.3v

The only successfully way to format my Nokia mirco SD 512 MB
was win / cmd(Admin) / diskpart .
( http://www.chip.de/bildergalerie/Windows-To-Go-So-laeuft-Windows-8-auf-USB-Sticks-und-Festplatten-Galerie_54926063.html)

Up to now I run the board stand alone.
OK Files:
- 000X.ad4
- 000x.wav   freq 12.000 Mono and -1dB

It is possible to run MP3 im stand alone modus ?

WTV020-SD module only can play WAV and AD4 file

Nice Stuff smiley

I will add my findings etc when I continue with my experiments. I am about to start smiley

The Datasheet says the maximum supported size of the Card is 1GB. Is that so or could you be able to use a card with higher capacity? I cannot imagine a reason of limiting the size at 1 GB because generally the address spaces are larger than that..  smiley-confuse

acctually it can support 2 GB,we have tested 2GB TF card,same use with 1GB TF card.some times manual will have something wrong,and we will revise them when we discover them.and welcome every one to help us point out them.

Hi the-rebel-agent,

Hats off for sharing your experience smiley

I am going to play with the same module but decided to ask and get the pin diagram confirmed. I found the following application circuit for this device.



I believe the following is the way of identifying the pins. Can you please confirm? smiley

Yes, the way of identifying the pins is right----waytronic -Jasmine. Manufacturer of WTV020-SD module
