This looks to be an interesting module:

MP3/WAV file player for $2...

I have ordered a couple to play with.  No pun intended.
Supports playback control via buttons, UART, OneWire or 8-bit parallel - very versatile!

Most modules have UART and many also have button control, but the OneWire and parallel control methods are interesting and useful.  Seven different operating modes are supported.

32Mb on-board flash storage(4MB) for music or sound files, and on-board audio amplifier for driving a speaker.  I would not put much faith in the 5W rating, but it will no doubt output plenty of volume to be heard.  The DAC output is on the pins, so you can couple into your own amplifier arrangement if you wanted to.  5v supply, with 3v3 output pin for powering other stuff(80mA max)

This would look to be perfect for embedded sound-effect type applications or any other annunciator type project.  Not really suited to music playback, cos of the limited storage space, but there are a plethora of modules that use micro-SD cards for those kinds of jobs.

Small, at only 26mm x 23mm, with the connections on a standard 2.54mm(0.1") grid.

I found the manual(and a whole heap of other docs) for this module with a bit of a poke around on the net, so I upload it to this thread.

If anyone is interested in the extended docs past this post, let me know and I can post a zip file.

I have no previous experience, but I remember owning a MP3 player in the early days that had 32Mbyte flash and could only store 6-7 songs on it. In 4Mbyte you will probably only store one song.

This maybe more suited to play some spoken word (short phrases), or play action sounds.

Changing the flash to a W25q256 is not a problem, I think. Then you would have 32MB onboard.
The question is whether the controller supports it.

That's an interesting idea.
As I have four modules coming, I might do just that, and see what happens.
The hard-coding in the controller/playback chip might be factory set for that specific 32Mb(4MB) capacity chip, but it would not hurt to find out.  

EDIT: Can't get the W25Q256 in 8-pin SOIC, it is only available in 16-pin SOIC or 8-pin WSON/WFLGA (QFN-like) package, so that one is out, but you CAN get the W25Q128 in SOIC-8, so I might get a few of those to play with.  If it worked, that would increase the file storage to 16MB instead of 4MB.

This may or may not work, but one way to find out is to.....
It is more academic then practical, as the effort to replace the FLASH memory chip on a $2 module is questionable, but there you go.  

EDIT: Opps!   W25W128 is the wide-SOIC(1.2mm wider package), which would be difficult to force-fit onto the narrow-SOIC footprint, so that idea is now out.  MIGHT be able to use the likes of a W25Q64(giving 8MB of storage), but would need to check the footprint-vs-package size thing again.  Might simply not be worth the effort.

EDIT: Hold the phone.....  Looking at the module again, it would seem that they DO use the wide-SOIC flash chip, so I CAN try out a W25Q128, but not the W25Q256, as it is not available in the SOIC-8 footprint.  You can easily see the size difference on the photo of the module in the PDF.

What about this one : 32MB MX25L25645 SOP8
Seems to be pin compatible according to the data sheet.
Does it always have to be winbond ?

Nice find.  
I will grab a couple of those to experiment with, along with some 25Q128's.
Neither may work if the controller is hard-coded for the 25Q32, but there's no harm in trying just for the hell of it!

"Please allow for up to 1cm size error!"  What are they measuring with, toddler finger widths?

Looks interesting. I have a couple but play track 123 is easy, no way to read the
track info ie artist though.

I also ordered one to play.

Found also the DY-SV8F board. Seems to be the big brother.
There is the same controller (DY1703a) and a 25Q64 flash onboard.
Think (hopefully) there is a good chance for upgrading the flash.

Yes, that is encouraging, considering it is the exact same controller chip.
I have looked all over google, I cannot find ANY data on the DY1703A chip.
If any member reading this has had better luck, please can you post a link here.
Normally, you can track down even a Chinese language version of a datasheet for chip X, but in this case, I can't find anything at all.
This despite the date-code on the chip in the pictures being 201903, suggesting it was made in 2019 or 2020 depending on how you want to interpret the code.
Normally just four digits, YYWW so 19th week of 2020, but could also be 3rd week of 2019.  I could also be neither of those at all!

Looks useful. Lots of info. Anyone used one?
They are just files on my from picaxe sd player, which is ok to use but no artist info which you get in win or linux.

Not the simplest thing to do but the required info is out there to achieve in MMBasic if you want to try.
http://mpgedit.org/mpgedit/mpeg_format/mpeghdr.htm
As a start, look at my File Manager for CMM2 program. Down the bottom of the mmedit page.

Looks like two flavors here

flash or SD

I successfully swapped the flash to a W25Q128.
What I can say is that the Mini Player behaves like a USB stick.
Windows formats the flash with FAT and then correctly shows 16 MB.
I copied a 5MB mp3 file and it works.  
The copying process takes longer, since it is writing into the flash.  

Next step a 25Q256 when these arrive

Well done!  
My modules have just arrived, but I am still playing about with the standard chip arrangement.  As I only ever wanted THESE modules for an annunciator project, having more then 4MB of storage is not an issue - for me.

But it is nice to see that you CAN swap the chip to get more space.
Please do keep us informed of what happens with the 256 chip.  

I had visions of a couple of things with changing the flash memory chip, and they were: (1) The DY controller chip may not support anything other then 4MB, and (2) the flash memory chip may have to be factory-formatted, meaning you put a bigger blank one in there, and Windoze won't be able to format it, as the DY controller does not know how or have the ability to mimic to the OS how to format it kind of thing.

Glad to see neither of those turned out to be the case.
Good to know.
