Is this the VS1033 or the VS1053? One does Ogg, the other does not.

From the chip markings, It looks like the VS1033.

Does it have 1.1 inches between the headers like every other MP3 breakout board sold at this fine establishment? Just thought I'd ask. I tried to measure from the photos, but quickly found I'm laughably horrible at keeping my mouse travel in a straight line.

And also laughably bad at good grammar.

Yes, it's the VS1053 that supports Ogg Vorbis/MP3/AAC/WMA/MIDI audio codec. I was really hoping tis breakout board would have had the VS1053 chip on it. The VS1033 is not capable of decoding Ogg Vorbis according to the VLSI datasheet. Is it possible to get this breakout board with the VS1053 on it instead? Thank you.

i am also interested in a breakout board with 1053 (1033 and 1053 should be pin compatible, so the baord for 1033 should work for 1053 too)

Just for my understanding (never bought from SparkFun yet).
Does this board contains the decoder chip or do i
have to order it separately?

Thanks.

Hello Huy! Yes, the breakout board does come with the vs1033 decoder chip soldered on, along with the supporting circuitry you see in the photograph.

Can anybody tell me what voltage level DREQ is supposed to be? For some reason my DREQ switches between 1.4V and 0V. I asked the forums but nobody answers..

NOTE TO BUYERS
the pictures are wrong, this comes on a red PCB identical to the VS1053 breakout board

This may seem like a dumb question, but what's the drop-out voltage of the on-board power supplies? If I'm running my dev board at 3.3V, does this mean I'll need a higher supply voltage to compensate for the drop-out voltage of the on-board supplies?

Also, what's the digital supply voltage? Will I need level translators for the SPI bus lines? (VLSI's website is currently down, so no data sheet right now)

Thanks for your help.

The schematics show a VCC which goes through regulators.
I assume the output of those are 3.3V based again upon
the schematic. I can only assume I can deliver 5V which
would be regulated to the 3.3V however I have no idea of
the regulators as they are not defined in the schematic.
SO....could anybody provide a bit more information so I don't let the smoke out of something????

From an audio codec newb: Is it easy to use this to encode voice, store it, then play back the stored voice? It says it records into IMA ADPCM (and user loadable? user-loadable Ogg Vorbis), but I don't see it saying it decodes IMA ADPCM.

This VS1033d MP3 decoder can't play properly unless you've got the TEST pin tied high. This is indicated in the VS1033 datasheet on page 14 ("Reserved for test, connect to IOVDD") and on the connection diagram on page 16. The engineers at VLSI pointed it out to us when we contacted them about our issues with this board.

We have been able to get the board to work when we create a solderblob that connects TEST pin 32 to CVDD3 pin 31. Make sure you've got a fine tipped soldering iron for the job!

wendyju, thanks for solving this problem!

I worked with the VS1033D board and it had extremely intermittent operation. If you moved a finger near it, it would emit static. But now I know it's because the test pin was floating.

Another warning: CVDD is powered at 3.3V (same as IOVDD) but the VS1033D datasheet says 2.7V is the maximum. Not sure what the implications might be, but it's definitely out of spec.

Are you sure that the regulator outputs 3.3V and not something like 2.8V? I can't measure the voltage because I don't have this board yet. I find it hard to believe that the designer of this board had made this kind of an error.
