Works good! The PDF file linked/provided on the Amazon product page is pretty good documentation IMO. I used Win 10, micro-USB cable, cheap earbuds & a cheap 32GByte TF micro-SD flash card (see pic). Win 10 recognized the flash card & I loaded 4 MP3 songs & 2 short wav sounds. Numbered them 00001.mp3 & 00005.wav, etc. When I disconnected the USB from the PC, I plugged it into a power-block to power the board back up. Listening with earbuds, I can hear each file played when requested by shorting the wire from the ground pin to the trigger pin. In the pic you can see I used a handy 10-Ohm resistor, but you could use a simple wire to trigger. In my project I plan to use pushbuttons to trigger the files. I didn't check the speaker-output or the power-input or the volume control. Notes: 1) There is PDF file documentation, as of today it is linked on the Amazon page, you may have to scan carefully to see the link. 2) You can power the board from USB, but if the USB cable is attached to Windows, the board will be in flash-drive mode, so you must switch to a USB power block, after you have copied your files in place. 3) The 3 DIP-switches select 8 different trigger modes. Read the docs carefully to decide which one you need. I tested all the discrete (button) modes, but not serial/UART modes. Lots of fun for Arduino fans. 4) I used a cheap 32-GigaByte TF/micro-SD card & I did not format it, so it seems to me the board handles this huge capacity standard format ok, but of course I have only loaded up a few MBs so far, so there may be some limits on capacity. I was able to play both MP3 & WAV files.

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!

Update: does not play .wav files at all. Original: 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.

After reading comments, I found the DY-HV20T module quite easy to use. Documentation in pdf format is available online. In basic mode (DIP switch in OFF, ON, OFF positions), the module allows playback of one of eight MP3 files (00001.mp3 - 00008.mp3) at a time by setting IO0-IO7 input low (to GND) momentarily. Other modes and external controllers e.g. Arduino will allow much bigger selection. Audio amp onboard can power single speaker, and with 12V supply it delivers good punch. 3.5mm audio output jack is stereo, but L-R channels are reversed (?) It's no big deal for hobby projects, but should be kept in mind. Maximum supported micro SD card capacity is 4 GB. Also note the built-in USB port is very slow compared to typical card readers. For the price, do not expect sound quality of expensive mp3 player, but overall, the DY-HV20T module is highly recommended for hobby projects like custom doorbells or Halloween props.

No matter what I did, it would not play any sounds at all. Waste of time and money.

Very nice product but couple of things to know. To load the microSD card, place it in the device, connect the device to your computer with a micromUSB cord, and it will show up in your drive list. Don’t try to load the card directly from your PC with an adapter; it won’t be recognized by the sound module. Also, the audio output appears to be a two conductor jack. Using a stereo cable gives distorted sound. Just use the tip and sleeve contacts of a cable and it will sound fine. Really neat product, as long as you know the rules.
