Product specifications:Power range: 3.7-5.5V Dimension: 45mm*36mm Packing included：1 x Mp3 Lossless Decoders Decoding Power Amplifier Review: For my application, where I need to play one sound on repeat this is great, real plug and play, so I can put it in an airtight enclosure without any switches or buttons needed to access. Hopefully it won't brake too soon. I connected it to a 30W tweeter speaker, as the sound I need is pretty high frequency. Works fine, louder playback as from any mobile phone. Will try with specified 3W speaker when I'll have one. Device will be powered from 12V battery trough a stepdown converter which will be operated with 12V photocell switch, so that playback can be started when it gets dark (or light). Easy to automate with simple light switch module just because there is no need to press ANY buttons for this player to start playing. Only bad thing - I ordered 12 pieces and they were packed about 8 separete packages mostly containing just one module and I have to meet the delivery man so many times. And just a note - volume level on auto start is about 85%, I would prefer it to be on 100%. For my application it would be easier to lower the volume in file, if needed. Review: 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 ## 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 | #85,038 in Electronics ( See Top 100 in Electronics ) #218 in Home Audio Amplifiers | | Manufacturer | DollaTek | | Package Dimensions | 12.3 x 8.8 x 1.1 cm; 14 g | ## Product Details - **Manufacturer:** DollaTek - **Maximum supply voltage:** 5.5 Volts - **Minimum supply voltage:** 3.7 Volts (DC) - **Mounting type:** Through-Hole 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) ![DollaTek Mp3 Lossless Decoders Decoding Power Amplifier Mp3 Player Audio Module Mp3 Decoder Board support TF Card USB - Image 2](https://m.media-amazon.com/images/I/619jso3EodL.jpg) ![DollaTek Mp3 Lossless Decoders Decoding Power Amplifier Mp3 Player Audio Module Mp3 Decoder Board support TF Card USB - Image 3](https://m.media-amazon.com/images/I/61MyX9f5+8L.jpg) ![DollaTek Mp3 Lossless Decoders Decoding Power Amplifier Mp3 Player Audio Module Mp3 Decoder Board support TF Card USB - Image 4](https://m.media-amazon.com/images/I/61AQTn9xDIL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by P***S on 6 September 2023* For my application, where I need to play one sound on repeat this is great, real plug and play, so I can put it in an airtight enclosure without any switches or buttons needed to access.
