Review: Great low cost DIY solution! - The most BASIC function: grounding pin IO_1 or IO_2 for play next or previous. Longer ground adjusts volume fine. Haven't tried using a library to program my Arduino and ATtiny85 for specific file play yet, but need to soon. The amp function works great with speaker positive to SPK_1, and negative on SPK_2 pins for mono audio on my 4 ohm 3 amp speaker in project box. MicroSD cards hold snug in slot and haven't popped out. NO discernable/significant heat from amp chip, which was a HUGE problem with the BY8301-16P MP3 Module that these replaced. Only issue is on 1 of the modules the header pins are soldered on somewhat slanted and take some fussing to insert in breadboard, but I'm not penalizing a star for that. Will update if I have problems with the Arduino library when programming for this, but until then, I'm very pleased with this purchase Review: None worked in an existing project - I had an existing project that uses this chip but from a different project, and it always ran fine. When I put these chips into that project, none of them worked at all. Poor quality. Save you money. ## Features - ❃❃ Item: MP3 Player Audio Voice Module. - ❃❃ The DFPlayer perfectly integrates hard decoding module, which supports common audio formats such as MP3, WAV and WMA.

Do you have two speakers connected to the module? I.e., from one of the SPK pins to a speaker and to ground, and another separate speaker from the other SPK pin and to ground? DON'T do that. Only connect one speaker, from SPK to SPK, unless you have an external amp. Why are you powering this at 2V? That's not normal. At 3.3 V, with no audio playing and no speaker connected, my module is only very slightly warm. You may have a connection error. **Q: Can it stop after each song and wait for a trigger to play the next song?** A: That's the way I used it. Played one piece, waited for a keypress or time-out (on Arduino), and triggered the next song. **Q: Can I hook up an 8 ohm speaker directly to this chip?** A: Yes but only one, between the two SPK pins. Do not do what some videos show, i.e., one speaker from each SPK output to ground. It'll work - right up until you fry the device. **Q: Does the microSD card need to stay in the slot to play sound or is it straightforward to store on the on-board flash?** A: The sd card has to remain in the unit. Mostly all of the boards you can easily interface with this module won’t have any decent sized on board flash to hold a music file. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great low cost DIY solution! *by D***T on 21 January 2023* The most BASIC function: grounding pin IO_1 or IO_2 for play next or previous.

When I put these chips into that project, none of them worked at all. Poor quality. Save you money. ### ⭐⭐⭐⭐ Finicky to get working, but cheap way to add music/sound to your project! *by P***R on 28 January 2020* 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! ## Frequently Bought Together - 3PCS Mini MP3 Player Audio Module MP3 Voice Decode Board TF Card U Disk IO/Serial Port/AD Board DFPlayer Audio Voice Music Module for Arduino - Dweii 4 PCS Speaker 3 Watt 8 Ohm Mini Speaker 8ohm 3w Loundspeaker Micro for Arduino with JST-PH2.0 Interface for Small Electronic Projects Advertising Machines LCD TV Monitors - HiLetgo 5pcs PAM8403 2x 3W Mini Digital Power Amplifier Board AMP Class D 2.5-5V Input --- ## 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.br/products/370408578-umlife-3pcs-mini-mp3-player-audio-module-mp3-voice-decode](https://www.desertcart.com.br/products/370408578-umlife-3pcs-mini-mp3-player-audio-module-mp3-voice-decode) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-05-28*
