Review: Reliable mono MP3 player - The MP3 player is easy to hook up and works well. It plays MP3s from a micro SD card or a USB drive or both. I found that it will automatically play whichever is plugged in. Or it will switch to the new one when one is plugged in. With the forward and back buttons I could step through the tracks from the SD card to the USB drive and back. I assume if I let it play it would play tracks across both from SD cart to USB although I haven't let it run that long. It also rememberd where I was when I powered it off and started back where I was when powered back on. I got sufficient volume from the speaker connection for anything I would want it for. The volume on the headphone jack was much lower. The headphone jack will work for headphones but won't drive a speaker without external amplification. At high volume there is some noticeable white noise. The only drawback I found is that it is mono not stereo. It has volume buttons (long press) and previous and next track buttons (short press). It doesn't have skip forward and back buttons which I find a requirement for listening to audio books or podcasts. It has a repeat track mode button and play/pause. Long pressing play/pause is supposed to switch back and forth between the SD card and USB drive but that didn't work.
Review: Great out of the box, and hackable - This decoder/player worked great for my project; a background noise generator. I recorded an air conditioner running and converted it to an MP3 file. Saved it to a micro SD card and plugged it into the player. Now when it's powered up, it plays the file. Easy. The board uses a GDP2856A chip for the decoding. Search Google for GDP2856A and you'll see that it has additional features (Repeat, Equalizer, Stereo output) that you can use if you have some electronics knowledge. You can interface it with an Arduino or other microcontroller too. Great value for the price. Paired with an appropriate speaker, (4 Ohm, high efficiency) the 2 watt output is more than enough to get the job done. See video- background noise, volume up, song playing.

## Questions & Answers

**Q: What do i label the files as? 1.mp3 ? 001.mp3 ? do i just load up a tf card and put it in the slot ?**
A: Does not matter how you label files. My plates is playing files in order they were stored to flush drive

**Q: Is this capable of loading and playing wav files?**
A: Yes. I have used both .WAV and .MP3 files successfully

**Q: there is absolutely no base on mine. is there any way to increase the base or should i just return it?**
A: You could 3D print a base. But if it's bass you seek then you need 10X the watts and a low-pass filter.

**Q: Where can I get the circuit diagram for this card? Looking to connect to arduino.**
A: All I was able to find is what's on the web page where you bought it.

### ⭐⭐⭐⭐ Works pretty much as advertized, but not much else
*by F***. on July 24, 2020*

This unit works well. For my application, I wanted something that would power up and start playing, which it does. It "remembers" the song played and remembers its "repeat" state. The LED blinks slow for normal play, fast for repeat play. As others have noted, there are no mounting holes or even very much empty board space for mounting. I didn't need the mono "speaker" output or the TF reader, so I soldered mounts to those pads. Also, the "batt" input isn't documented. There are vias through the + and - power leads and this makes them pretty easy to use. Hopefully secure that the pads won't pull off. I found the push buttons are so close together that it's difficult to get all four panel holes and mounts close enough together to engage them. It would have been nice if the layout put them farther apart. I'll probably solder leads across "Play/pause" and use a momentary remote switch, since this is the one my application needs most. These pads do NOT have vias, so it will be important to strain-relieve them, somehow. Overall one point off because it doesn't seem much thought went into mounting. Two points off "thickness" because it's so irregular as to make it hard to mount with buttons and LED facing the panel. If you're going to mount to the back of a box and poke at the buttons from the front, then it would be fine.
