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 January 21, 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. ### ⭐⭐⭐⭐⭐ Fun project *by R***N on November 22, 2024* Putting sound to a fuzzy toy for my granddaughter. No arduino needed for sound. I threw a few Mp3 files onto an sd card and labeled 0001-0005. Power supplied by single Lipo 18650 4.2v battery salvaged from old laptop. Wired four switches in series #1 direct (resistors needed) #2 1k ohm #3 6.2k ohm #4 9.1k ohm and works great. Her toy growls, giggles, hums and farts. Next project is record company radio chatter and place one behind a dispatch desk to drive people nuts. Cheapest part of whole project was the card. Schematics are online or lookup HackMakeMod on YouTube for a short tutorial. ## 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? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/164241082-3pcs-mini-mp3-player-audio-module-mp3-voice-decode-board](https://www.desertcart.co.uk/products/164241082-3pcs-mini-mp3-player-audio-module-mp3-voice-decode-board) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-16*
