Has anyone tried this module from Elechouse?
I purchased 2 and can't make either of them work on Arundio MEGA2560.
I've uploaded the Arduino code plus audio sample that comes from the elechouse website.
Any advice would be appreciated.

According to it's datasheet (in the manual) it uses SDA & SCL that are on A4 & A5 of UNO but they are somewhere else (pins 20 & 21) on Mega.

There appears to be no shield jumpers to move the SCL/SDA lines so an option might be to cut these pins off the underside and jumper across the top (assuming your not using another shield stacked on top.

Thanks Riva.
Rather than modify the board I've just ordered a UNO.
I'll let you know how/if it solves the problem.

Hi Riva,
Attached it to a brand new UNO and it still does not work

Has anyone here had any experience with this module on any version od Arduino?

UPDATE:
I always admit it (well almost always) when I stuff up and Nerds and Nerdettes I have stuffed up!
The problems I have been having with this module have been due to a labeling error I made on the SD card.
Me BAD!
Thanks again Riva for trying to save me from myself.

So does it also work one your Mega or just the UNO?

Works on both the Uno and the Mega
In case someone - one day - does a search of this Forum in response to problems with this module let me document here that if you make wav files for it they must be mono, 8 bit and slower than 14KHz or it doesn't run,. You have been warned.

hmmm, that's not so hot.  Thanks for the info.

I'm working with a wav shield by Adafruit (or ladyada) that supposedly handles 16 bit, 22kHz, FAT32 and SDHC.  I'm not up and running yet, but they've had this one out for a bit, and it's rev 1.1.  I'll try to let you know how it works out.  Uno is my platform at this point.

I may be pressed for processor power and working memory space, but I don't know if 8bit and that low a sample rate can give me workable fidelity for my purposes.
