I bought it because I would get three for the price of one original DFRobot mp3 player. But this doesn't work with Arduino, I tried everything that I could think of.
It works standalone so the circuit is working but I think issue is with the firmware.
So, if you are planning to use it with Arduino buy the original one. I learned the lesson after soldering :(.
Turns out there was some shorting on my board with the serial terminals. This player was probably ok. So changing to 5 stars.

Finicky to get working, but cheap way to add music/sound to your project!
It took me awhile to get this thing up and running. Unbelievably, most wiring diagrams and test code I found online were wrong! I used this with an Arduino Pro mini 328 (functionally the same as an UNO). I could not get the hardware serial encoding to work, so I had to use software serial encoding. I could only get the software encoding to work with the library AltSoftSerial on pins 8 and 9, with 1Kohm resistors on both RX and TX pins. You also MUST use an external power supply! I could not power up the chip from the arduino USB power for whatever reason. There is a small red LED at the top of the DFPlayer, and it must be illuminated. If its not lit up that's your first problem. The speaker should be hooked up to speaker + and speaker -, not from speaker + to ground. If you want stereo sound you need to use the DAC outputs. Many people say that have to connect both grounds. It worked fine (without any noticeable noise) only using the ground near the speaker terminals, but it is smart to connect both grounds together. The way you organize your MP3 files is extremely important. It read a 32gB card formatted in FAT32 just fine. I converted all my MP3s to constant bit rate (many you download with be variable bit rate) . I don't know if this can read variable bit rate, but I didn't take that chance. If you want to play the files off the root directory, you must name the files with a 4 digit number, for example "0004.mp3". HOWEVER, if you want to use several folders to play different sounds, i.e. 30 files in folder 01, 30 files in folder 02, etc. you must name the sounds with a 3 digit number, i.e. "004.mp3" in folder "03". After getting all that figured out, its a neat little device! Only uses 2 pins and about 10% of memory. You can change the volume and a bunch of other stuff via code. I have about 100 small MP3 files on my SD card and there is no noticeable lag when playing. The sound quality and volume is pretty good for such a small chip, if you have a decent speaker (3w max) hooked up to it. WAY better than using any sort of onboard noise making on the arduino. And once you send the play commands, the DFPlayer plays it stand alone without using up too many Arduino resources. Great for any arduino sound project!

These are pretty terrible clones using TD5580As instead of what's pictured in the listing. It didn't work with existing Arduino libraries out of the box. They technically "work" as a standalone player with the correctly formatted files, but no matter how much I isolated the player itself, I'd get hissing and static on the 2 of the 3 modules I tested, and that's with 3 different speakers that worked fine on standalone amp boards. Normally, I'd try to just put up with whatever shortcomings a cheap clone might have, but I don't have time for this headache when the original DFPlayer is just a few bucks more.

I used this device for a music player project. It worked fine for my purposes. Credit to "Richard Makes Escape Rooms" for his tips on using the serial command API. Project source, pictures and video link on my rshorton github music_box project.
Worked well for music player project for granddaughter
