Product specifications: Power range: 3.7-5.5V Dimension: 45mm*36mm Packing included： 1*Mp3 Lossless Decoders Decoding Power Amplifier Review: The product was used for a sound system in a model steam boat Unit works perfectly Review: The MP3 player is easy to hook up and works well. It plays MP3s from a micro SD card or a USB drive or both. I found that it will automatically play whichever is plugged in. Or it will switch to the new one when one is plugged in. With the forward and back buttons I could step through the tracks from the SD card to the USB drive and back. I assume if I let it play it would play tracks across both from SD cart to USB although I haven't let it run that long. It also rememberd where I was when I powered it off and started back where I was when powered back on. I got sufficient volume from the speaker connection for anything I would want it for. The volume on the headphone jack was much lower. The headphone jack will work for headphones but won't drive a speaker without external amplification. At high volume there is some noticeable white noise. The only drawback I found is that it is mono not stereo. It has volume buttons (long press) and previous and next track buttons (short press). It doesn't have skip forward and back buttons which I find a requirement for listening to audio books or podcasts. It has a repeat track mode button and play/pause. Long pressing play/pause is supposed to switch back and forth between the SD card and USB drive but that didn't work. ## Features - With high quality, onboard 2W single channel power amplifier. - Convenient to wire and refit; 4 buttons on the board for setting operation. - Support MP3 format, playing power on automatically, LED indocator light when module is working. - Mp3 lossless decoders power amplifier Mp3 player module Mp3 decoder board support TF card and USB. - Support TF Card (mobile phone memory card), U disk playback mode With the speaker terminals without welding. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01DK9SL6C | | Best Sellers Rank | #79,478 in Electronics ( See Top 100 in Electronics ) #211 in Home Audio Amplifiers | | Brand Name | HiLetgo | | Customer Reviews | 4.4 4.4 out of 5 stars (214) | | Manufacturer | HiLetgo | | Material Type | Plastic | | Maximum Supply Voltage | 5.5 Volts (DC) | | Minimum Supply Voltage | 3.7 Volts (DC) | | Model | 5582718094 | | Mounting Type | Through-Hole Mount | | Number of Channels | 1 | | Output Power | 2 Watts | ## Product Details - **Brand:** HiLetgo - **Manufacturer:** HiLetgo - **Maximum supply voltage:** 5.5 Volts (DC) - **Minimum supply voltage:** 3.7 Volts (DC) - **Mounting type:** Through-Hole Mount ## Images ![HiLetgo Mp3 Lossless Decoders Decoding Power Amplifier Mp3 Player Audio Module Mp3 Decoder Board support TF Card USB - Image 1](https://m.media-amazon.com/images/I/61Wks2IK-UL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: What do i label the files as? 1.mp3 ? 001.mp3 ? do i just load up a tf card and put it in the slot ?** A: Does not matter how you label files.

Have it connected to turn on and off with the fireplace. Adds another layer of authenticity to an already excellent gas fireplace. Amazed they don't come with sound as an option. ## Frequently Bought Together - HiLetgo TF Card U Disk Play MP3 Decoder Player Module with Audio Amplifier Audio Decoding Player Module Micro USB 5V Power Supply - Nano V3.0, Nano Board ATmega328P 5V 16M Micro-Controller Board Compatible with Arduino IDE (Nano x 3 with USB Cable) - 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.hr/products/256334303-hiletgo-mp3-lossless-decoders-decoding-power-amplifier-mp3-player-audio](https://www.desertcart.hr/products/256334303-hiletgo-mp3-lossless-decoders-decoding-power-amplifier-mp3-player-audio) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-17*
