it supports micro-sd cards and it can play also wav files (that i prefer than mp3, because of lag at begin of each track)
Key Features
Built-in 1W amplifier, can directly drive 1W/8? speaker.
BUSY output port available.
Support SPI flash and micro SD card as the meories at the same time.
Standard 5 Keys MP3 player, and a ADC key available to A Special function key,play next sound when press it short time,and Loop current sound. Copy data from TF card to Flash only by pressing key long time.

Great stability for long-time playback and strong anti-interference ability.
Support ·FAT16,FAT32 file system
Support 16Kbps~320Kbps bit rate and 8KHz~44.1KHz sample rate MP3 and WAV two format file
Looks like almost everything I have been looking for in a MP3 module. The only thing missing is the ability to open any file into the microcontroller. It does seem to have the SPI pins coming out to the connector, so I think you could do that with the SDfat library, but it would have been nice if the module did all the FAT stuff for you.
Of course the datasheets and info I have found are such horrible english that maybe it does support that somehow and it isn't clear.
I think I will order one as well. Would be nice to make a library for it, anyway.
Waytronic-Jasmine(Li):
If you store in SD card,the module only can support 16Kbps~320Kbps bit rate and 8KHz~44.1KHz sample rate MP3 and WAV file.
thanks for your informations and welcome to the forum, very nice to have Waytronic support here
so you confirm it can read wav files, this is very good for my project because the Mp3 files have always a very small lag at beginning of each track (it's a well known codec issue) that doesn't fit my project (sound must start when led turning ON, without lag)
today i received the module
while plays mp3 files without problem and with a very good quality, i can't play wav files
tested 8bit 80kbps 22khz without success
something odd: if you want to keep the files order, firse must create the mp3 playlist on hard disk (0001.mp3, 0002.mp3, ecc) and when ready copy to the micro-SD card. If you rename on microsd card it will messy the order.
I used 2 watt stereo speakers @ 8ohm: if used in mono no problem, when stereo you can hear clipping. With a mini amplifier no problem at all also in stereo mode.
const int buttonPinFire = 7; // FIRE
// variables will change:
int buttonState = 0; // variable for reading the pushbutton status
void setup() {
// initialize the button pin as a input:
pinMode(buttonPinFire, INPUT);
// initialize serial communication:
Serial.begin(9600);
Serial.write(0x7E);
Serial.write(0x03);
Serial.write(0xA7);
Serial.write(0x1F); // volume max
Serial.write(0x7E);
// start sound
Serial.write(0x7E);
Serial.write(0x04);
Serial.write(0xA0); // A0 for SD card
Serial.write((byte)0x00);
Serial.write(0x02); // track number
Serial.write(0x7E);
delay(3000);
}
void loop()
{
buttonState = digitalRead(buttonPinFire);
if (buttonState == HIGH) {
Serial.write(0x7E);
Serial.write(0x04);
Serial.write(0xA0); // A0 for SD card
Serial.write((byte)0x00);
Serial.write(0x01); // track number
Serial.write(0x7E);
delay(300);
}
}

With all of these modules, the name doesn't matter. It is the actual order that they are found in the directory entry table. So, if you were to name your files 001.mp3, 004.mp3... and then copy 004.mp3 first, then 001.mp3, it would make 004.mp3 track number one and 001.mp3 track number 2.
So you can name the files however you want. But you must be careful what order they are in the directory entry.
To make things easy, just copy all your files over and use this program:
to sort where the files are put in the directory entry. Pretty much all of these modules have this same issue because they use a very simple FAT access routine.

Great! I read the manual and was not that clear how to connect it or program it. Do you have a new manual or just were lucky connecting it?
i just followed the data sheet
there is the WT5001M02-28P pin assignment scheme (page n. 10). On the board the first pin on the left is labeled "1" as you can see on the magnified picture.
The 5v input is the vdd50 pin 22.
From pag. 14 you can find the serial commands to use with arduino.

you are right. If i am going to make any change of the file order i will first copy the root of the microsd to the hard disk, and when finished i will copy again from the hard disk to the micrsod.
wav files are supported (44.100hz/16bit/stereo) but with issues: files start to play only after 1 or 2 seconds of blank sound with a fading-in effect. tried to lower the sampling rate without any change.
This module looks like a fun one to write a library for. It seems to support a lot of neat features that are confusing in the datasheet. I still need to pick one up, but all sources I have found are in China which for some reason right now is taking over a month to arrive here in the U.S.
I suspect that fading-in is probably some feature that is set somehow and not well documented. Otherwise, it wouldn't make a lot of sense to do it as it would actually take more effort to fade in than to just play.

i don't know but with mp3 files everything is fine (no fade-in effect)

It is possible to connect the files to buttons?
For example if i press button 1 it's gonna play the file 1, press 2 play file 2 and so on??
My second question is that i want to loop the sound files so when i press the button it is starting the file, and the playing is countinous ( repeat the same file endlessly) until i press another button.
If it is possible can you give me a hand how to do it?
What is the lowest voltage this module works at? I ordered one two weeks ago, probably need to wait another two weeks for it to get here. Would just like to do my planning. I will have one/two/four LifePo4 batteries that deliver +3.3V each. I would prefer to stay at 3.3V rather than going to 6.6V and have a regulator waste alot of my voltage
On pages one and two of the datasheet it has this for voltage: 5.0V - 3.3V; 3.3V - 1.8V
On page three it says -0.3V - 5.2V
On page four it says 3.3V minimum to 5.2V maximum
We will do english manual better in future
