DFPlayer - A Mini MP3 Player

This works magnificently. It’s one of nature’s greatest feats. I was able to quickly piece together a device that Rick rolls my friend at random, and planted it under his bed. I had carved a small hole in his bed frame, big enough to fit the device, but small enough for me to seal it off with sunflower seeds and glue. He’s slowly losing himself, waking up in the middle of the night and not being sure where the sound is coming from. Car battery in his floor boards will allow my device to run for a lifetime. It’s over Kyle, I’ve won. You may have told all of our 6th grade class that I pissed my bed, but who’s laughing now? I am, Kyle. I’m the one who’s laughing because now— with your wife and kids— you suffer the inevitable and everlasting sound of Rick Astley’s talented and angelic voice project through your body as you sleep, never being able to rid of it, and never knowing if it’s all just in your head. Checkmate, Kyle.

Worked well for a project I was working on. Easy setup and plenty of documentation to find online. No complaints and worked out of the box which is always great for something cheap like this!

I needed a few DFPlayer Mini's for a hobby project I was working on. I am by no means somebody who creates electrical circuits, but creating something with ESPHome by following some simple instructions online is something that I have no problem with.In this case, a simple doorbell chime. The idea was:- Take a Wemos D1 mini and a DFPlayer mini- Use the 5v pin of the Wemos D1 to power the DFPlayer- Connect 2 GPIO pins between the Wemos D1 and the DFPlayer for data communication- Connect the speaker to the DFPlayer- Upload an ESPHome sketch to the Wemos D1Straight forward, right?Well, it is - As long as you use the original DFPlayer. I purchased a few clones since 5 of them cost the same as this single board.I could not get it to work, tested with all 5 clones for a few days. Then I decided to order this one. When it arrived, I simply replaced it on my breadboard, and like magic, everything worked.Don't waste your time or money with clones, especially if you are a tinkerer like me. Just get this one. It just works.

These worked great on a homemade project to build a 3D dog replica.

After struggling to get the HiLetgo version of this to work, I finally concluded that the HiLetgo versions were probably broken and I should try a different one. So I bought this one--which is perhaps the real-deal, as it is Sold By "DFRobot"--put it on my breadboard with proper connections, used the DFRobotDFPlayerMini.h library + software serial... and it worked!!!Strongly recommend this over marginally cheaper versions.

Seriously, these seem like a fun project, but they're not. Just avoid these at all costs.I wanted to make a music player for my disabled daughter that she can use herself. I'm no expert, but have done several similar small projects with little trouble. However, these players are nothing BUT trouble.When I first started the project, I bought the cheaper clones to try to save a few bucks. Those wouldn't even read the values off the SD card properly. I read that it's a clone problem and only buy the legitimate ones, which these are supposed to be.Are they better? Yeah, maybe. They do read the SD cards. The first one I bought I had mostly working, except for volume controls which would do all kinds of weird things, like gradually increasing the volume without any input. I got it working at a set volume, and could have lived with that, but I decided to go with a different form factor and did not want to unsolder, so I bought another.Well, number 2 would only accept one play command. When I would send a second command of any kind, the chip would lock up and not respond further without resetting the microcontroller. Can I live without being able to switch tracks? No.So, I stupidly bought a third chip. Hooking it up, it immediately constantly sets the busy pin to low, which none of the others were doing. This indicates to my code to play another track, meaning, you get a second of audio per song. Maybe I could work around this, but I'm giving up.It's possible these are good at the factory, I cannot say. They are terribly packaged for shipping. The pins are pushed into a piece of foam on that one side, that is shoved in (I think) an anti static bag. Then they ship from amazon inside a bubble envelope. There's not much to prevent the business side from getting slapped around or jammed between other packages, which given Amazon, I'm sure it is.Find a different hobby project, for your sanity.

I had a single audio file I wanted to play on queue for a Halloween decoration. After attaching to an ESP8266 and loading a uSD card with the WAV file this thing just worked the first time.Can't ask for more than that.

works OK is a pain in the ass to work with and set up
