Measuring just 20x20mm and weighing 20g, it supports up to 32GB external storage and features a 24-bit DAC for superior audio quality. Compatible with MP3, WAV, and WMA formats, it offers flexible control options and built-in equalizer settings, making it the go-to choice for reliable, professional-grade sound integration in space-constrained applications. ## Description desertcart.com: DFPlayer - A Mini MP3 Player for DIY Arduino / ESP32 Sound Project : Electronics Review: The True Blue DFPlayer - A first Look - The DFRobot DFPlayer was tested in both serial communications and hardware loop mode. There are many clones of the DFPlayer, some are compatible, "partially" compatible or not at all. This one is compatible in either mode and is a good player to start or for reference to compare to the clones. The DFPlayer is powered by a separate 5V supply with both its grounds connected together. A 1k resistor was connected in series with the RX line for serial communications mode testing. There are 3 ways to connect outputs, a single speaker which is mono, headphone mono output, and DAC output for stereo. The DFPlayer sound quality is dependent on the speaker and it is quite good especially when a separate audio amp is connected to the DAC outputs. The DFRobot DFPlayer sells at a 4-5x premium compared to DFPlayer clones and while they can be made to work in most cases, the DFRobot DFPlayer provides the best chance for success. I had a spare SD card to test prior to buying the DFPlayers. Unfortunately decided to return them solely due to the unexpected huge increase in flash memory or micro SD cards. Will delay the project until memory prices return to reasonable. Review: Just works - Don't bother with the fakes ones! - 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 D1 Straight 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. ## Features - Mini Size, Massive Storage Expansion: Measuring just 20mm*20mm and weighing 20g, the module's compact size makes it perfect for integration into space-constrained products.

We recommend using this specification for optimal results. **Q: I tried to install this module to esp8266 rx to rx and tx to tx but i got the error message rechcheck your connection and insert sd card??** A: Think of RX as listening and TX as speaking. If you connect RX to RX (listening to listening), there is no data being exchanged. You need to connect RX to TX and TX to RX (speaking to listening). Hope this helps. ## Customer Reviews ### ⭐⭐⭐⭐⭐ The True Blue DFPlayer - A first Look *by M***R on July 18, 2026* The DFRobot DFPlayer was tested in both serial communications and hardware loop mode.

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. ## Frequently Bought Together - DFPlayer - A Mini MP3 Player - Dweii 4 PCS Speaker 3 Watt 8 Ohm Mini Speaker 8ohm 3w Loundspeaker Micro Speaker for Arduino with JST-PH2.0 Interface for Small Electronic Projects Advertising Machines LCD TV Monitors - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/218772246-dfplayer-a-mini-mp3-player-for-diy-arduino-esp32-sound](https://www.desertcart.com.ar/products/218772246-dfplayer-a-mini-mp3-player-for-diy-arduino-esp32-sound) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-08-18*
