You can buy the same one here:
http://www.ebay.com/itm/160806790230?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

and I do believe this library will work with both.


The only difference is the chip packaging. (DIP 16 and SOP 20) There are no functional difference between two sub-models. So the-rebel-agent's library should work perfectly with both the types. If you need more details on the difference of the package (I don't think you need  :P) you can find it on http://letsmakerobots.com/files/WTV020_manual_V1.3.pdf

Hi everyone!

I bought one of these on ebay, trying to use as sound module for portal gun replica. I wired up as data sheet suggests, connected to my arduino lilypad, and tested. No sound from piezo speaker, busy led flash 2 or 3 times then full on constantly.

I'am using a Sandisk 1gb micro-SD, has anyone tested one of these to see if they work?

Thanks in advance!

(let me know if you would like video/pictures of setup, i can provide later)

Are these things correct?

1. Did you convert your files to AD4 format?
2. Is the naming convention of the files correct?
2. Do you know your SD card is "supported"?

I am successful in using a SanDisk 2GB so I believe your sandisk 1Gb should work without any trouble. The best way to verify this is to use a SD shield or Ethernet shield just to verify your MicroSD.

Hey.

1: Yes the files were converted. Just to make sure I downloaded the test file made (and tested) by another user on these forums.
2: As far as I am aware, I just needed to copy the files named 0000.ad4, 0001.ad4, etc to the SDcard root dir?
3: Ok. If the file tree is correct, then I will try a different card.

I don't have a shield to test it with, as money is tight at the moment, and I've never needed one. Please let me know about the file tree if you can, as I can't find any info about it on the web. Cheers!

Hey everyone,

I've been working on the WTV020-SD-MINI for about 1 week but to no avail. After reading up almost everything posted on the web and utilizing all the files that were shared which proved to be working, I'm still not getting any sound except a few bleeps when the busy pin's LED blinks. I'm currently using a 1GB Samsung uSD card and I think that it is the culprit.

I will be changing this uSD card to a Sandisk soon and hope it will work, fingers crossed  :smiley-roll-sweat:
Will get back to you guys soon after changing the uSD.
