Worked great right out of the box. Converted Itunes files to .wav format. Insert an SD card and plug the board into my computer via USB. The board shows up like a USB drive. Moved the .wav files to the onboard SD card and renamed each file 00001, 00002, 00003 etc. There are IO pins and a ground pin on the side of the board, just solder a momentary button switch between the IO pin and the ground. Press the button corresponding to the IO pin and the .wav file will play. Great deal for what it does.

The speaker output doesn’t work at all if you’re powering it with the USB-micro connection but the headphone jack does. Otherwise the device works correctly on USB power. When you apply a 12v supply the speaker works fine.The file names have to be 4 zeros and a digit. If you use 5 like I did then the only mode that will work is mp3 play all because that mode doesn’t care what the file names are, it just loops through whatever is there.The volume up/down control is awkward and the default is full volume which is pretty annoying. I get that it’s hard to choose what level to use but going all the way to the highest setting seems a poor choice.I used a 32G (BYTE) card having not read the fine print where it says 32G BIT (4Gbyte). I formatted it on an iPad using the Files app which resulted in a clean 32Gbyte card. I used a 3rd party cheap usb adapter with an sdcard reader. I copied some files out to it and renamed them in place and this worked fine, probably because it was a fresh card so all the files went into blocks at the start of the device and none extended beyond the 4Gbyte limit. That says if you format it first and don’t get carried away a 32G card will work. I have tons of them and exactly zero 4Gb ones.Other than the super annoying full volume default I like them.

I dont have an electronics background, so getting it to do what I want is challenging and time consuming. I want a separate button to play each pre recorded message. Ive searched you tube videos but they dont explain how to do this. Plus I want to be able to change the recordings easily at any time. Does not come with instructions, you're on your own.

Used these in a puzzle box to control sound effects and these worked great. No real delay. Used transitor as open drain to control pins from arduino. But does have option to use uart which would maybe have been easier.

The most frustrating aspect is the lack of documentation. I can find nothing on the internet in way of a manual. I've wasted hours trying to get a sound out of the audio or speaker port. I can plug the board into my Mac and it recognizes it, but what format should I use on the SD card? I've tried them all, MSDOS, MACOS, EXFAT, etc. with no success. I've loaded MP3 files with the naming convention with no success. Is it too much to ask PEMENOL to publish a manual? I don't like returning hobby boards, but I've wasted way too much time on it. My next move is to buy a board that has a manual.

Only thing I would of liked is maybe a screw terminal instead on soldering

Although the board looked a little different than the photos provided ( no components soldered onto the board, near the I/O ) everything works and functions great. I run this board in USART mode, controlled by Arduino. I loaded up the "SnijderC DYPlayer" Library, opened the example code provided, and was able to play audio first-try.As others mentioned, the MP3 files need to be named 0001.MP3 so when you address song 1, it'll play that song. I used a 3.3V arduino, I don't know if the pins accept 5V. But, I can vouche they accept 3.3V no problem.I used this board to play little sound clips to add sound effects to a project. I found it very user-friendly the board doesnt have power/speaker connectors. This allows more customization to the user's use case., I was able to fit JST-XH connectors on, as well as adding generic pins for the I/O. Simply gave it power and ran only 2 wires to the arduino and I got full control. The potentiometer on the board sets the "max volume" and the arduino can digitally control 0-100% of the volume, set by the potentiometer. Very happy with the end results!

This is certainly a powerful and flexible sound module, which works well.Points of clarification:- this board uses a 4 gb TF memory card, not a 32 gb card. Don't buy the wrong one!- the board control inputs are 3.3 volt logic level, not 5 volt TTL (not mentioned anywhere in the docs - reverse engineered it to figure it out). Open collector / drain drive drive works well.- no docs come with the board, but there is a link in the web page to download them
