today i received this sound modules i ordered on ebay hong kong, they should accept serial commands as confirmed by the seller. What i don't understand is the version i got. On the ebay auction it was showed the "V1.4" and the description says "DC2.5 ~ 4.5V"
Now this board shows "V1.5 / 2012.01.12", and "5v / 3.3v"
that means i can power it via arduino 5v?
someone have the right datasheet for this version? i have found this one but it's outdated.
I sent an email to the seller, waiting the response.
