Put a SD card in and it just plays on power up. The quality seems good. You cant easily select a file though, its use is for something like music on hold or for sound effects. As an engineer I would also warn the output is not filtered very well. IE along with the audio theres a load of high frequent digital noise, you cant hear it but it might affect some amplifiers. ## 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 | B07M6JWMH6 | | Best Sellers Rank | 19,486 in Electronics & Photo ( See Top 100 in Electronics & Photo ) 136 in MP3 & Digital Audio Players | | Brand | DollaTek | | Country Of Origin | China | | Customer Reviews | 4.5 out of 5 stars 91 Reviews | | Manufacturer | DollaTek | | Material | Plastic, Metal | | Maximum Output Power | 2 watts | | Maximum Supply Voltage | 5.5 Volts | | Maximum supply voltage | 5.5 Volts | | Minimum Supply Voltage | 3.7 Volts (DC) | | Minimum supply voltage | 3.7 Volts (DC) | | Mounting Type | Surface Mount | | Mounting type | Surface Mount | | Number of Channels | 1 | | Number of Items | 1 | | Number of Packs | 1 | | Output Power | 2 Watts | | Package Type Name | Blister pack | | Specification Met | CE | | UPC | 725835035354 | | Unit Count | 1.0 count | | Voltage | 5.5 Volts | ## Product Details - **Manufacturer:** DollaTek - **Maximum supply voltage:** 5.5 Volts - **Minimum supply voltage:** 3.7 Volts (DC) - **Mounting type:** Surface Mount - **Voltage:** 5.5 Volts ## Images ![DollaTek 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/61-XAO1g24L.jpg) ## Questions & Answers **Q: what ohm are the speaker outputs rated at please?** A: 5 volts 3 watts = 8 Ohms ( I think ) **Q: Could this be connected to an Arduino to play a sound on motion trigger or something like that?** A: I'm not sure as I used mine in side a little church to play some Christmas songs with some rgb lighting. ## Customer Reviews ### ⭐⭐⭐⭐⭐ awesome audio boards *by D***R on 10 November 2025* absolutely awesome product for my Johnny 5 model project, once paired with a good mini speaker it gives clean crisp sound, the only downside is it doesn’t have a play once option and wished it could handle more power (as ive burned through a couple lol) but in all good cheap audio boards for projects ### ⭐⭐⭐⭐⭐ Great little module *by B***N on 16 March 2025* Great little module.
