It offers versatile control via UART, I/O triggers, and single-bus serial port, making it ideal for embedded audio applications requiring high-quality playback and easy file updates. ## Description Features:Support MP3 and WAV decoding format.Support sampling frequency (KHz) : 8/11.025/12/16/22.05/24/32/44.1/48.24-bit DAC output, dynamic range support 90dB, SNR support 85dB.Support 64Bbit(8Mbyte) Flash memory.Support UART serial port control voice broadcast function.It can control playback, pause, selections, turn up and down volume and other functions, the largest selection of 65535 songs.The baud rate is 9600 bit/s.Support I/O trigger function, 8bit I/O ports can trigger 8 musics or 8 I/O combinations to trigger 255 songs.Support One_line single bus serial port control, which can control playback, pause, selection, turn up and down volume and other functions.Support 3 configuration I/O for mode selection to make 7 work mode.Built in 5W Class D amplifier circuit and can directly drive 4ohm 3~5W speaker.Parameters:Work Voltage:DC 5VWorking Temperature range:-20℃~85℃Working Humidity range:0%-95%RHSize :35*35*4.5mmPackage:1 x Voice Playback Module Review: Davvero semplice da usare, si caricano i wav o mp3 numerati, come fosse una chiavetta (per quanto lentissima) e poi, nella modalità base, basta portare i pin a ground e parte il suono. Credo abbiano delle resistenze di pullup integrate. Con arduino si puo' attivare il suono passando dal pin in modalità INPUT (ad alta impedenza) a OUTPUT LOW per qualche millisecondo e poi tornare INPUT. Unica "pecca" è che i suoni non partono proprio istantaneamente, c'e' un leggero delay (una frazione di secondo) da quando il pin va a ground a quando parte effettivamente il suono. Almeno, io osservo questo, non so se possa dipendere dal mio setup ma non credo. Anche il wav che ho testato e' corretto senza silenzio iniziale. Ho provato solo la modalità "semplice" quella di default (un pin, un suono), non quelle piu' avanzate, non ne avevo bisogno per il mio progetto. Segnalo anche la board SV5W che e' simile ma sfrutta una scheda SD invece di una memoria interna (se gli 8 mega non vi bastano) In ogni caso, davvero un modo indolore per integrare dei suoni preconfezionati nei nostri progetti Review: Recognised by Win 10 PC as a USB drive by simply plugging into the Micro USB port. Comes pre-configured with 9 small MP3 files each one contains the voice of someone speaking the file number in Mandarin, simply replace these files with your own renamed ones and you are in business. The most important information relates to the 3 mode switches which change the way the playback mode is triggered, I have attached this missing information here for you. I could not find their own web site for help. It is possible to interface to Arduino as well, simple coding, again you need to search for that information. A very good value device for adding sounds, voice or alerts to your home projects. Does not come with data sheet, header pins or a USB cable, or a speaker but that keeps the cost down. UPDATE: Couple of extra points: These boards are very dependent on a good supply voltage - lower supply to 4.2V it will still function but only at lower volumes, so you will need a buck converter supply to run from a 3.7V LiPo cell. Another issue is that in stand-alone mode, triggering inputs with a solid ground (which remains grounded) produces constant repeat playback of the relevant sound file over and over. Only by removing the ground (or power) will stop the playback, these boards are not single-shot playback so it may be necessary to employ schmitt trigger circuits if you need to prevent this or use the Arduino UART mode. None of the three program switch positions have any affect on constant repeat playback, which is a shame for my application. ## Features - This module integrates I/O subsection triggering, UART serial port control, ONE_line single bus serial port control. - Onboard 5W Class D amplifier circuit and can directly drive 4ohm 3~5W speakers. - It can connect the computer to update audio files via USB cable. - 3.5mm audio interface, Micro USB download interface, button module in one module. - Support MP3,WAV decoding format.Support 64Bbit(8Mbyte) Flash memory. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BVQKYZ5C | | Brand | DollaTek | | Built-In Media | 1 x Voice Playback Module | | CPU Model | Core M Family | | Compatible Devices | 3.5mm Audio-enabled Devices | | Connectivity Technology | USB | | Customer Reviews | 4.1 4.1 out of 5 stars (37) | | Item Dimensions L x W x H | 35L x 35W x 5H millimeters | | Manufacturer | DollaTek | | Memory Storage Capacity | 8 MB | | Mfr Part Number | CP020246 | | Model Name | DollaTek Voice Sound Playback Module | | Model Number | CP020246 | | Operating System | Linux | | Processor Brand | ARM | | Processor Count | 1 | | RAM Memory Installed | 0.01 GB | | RAM Memory Technology | DDR4 | | Total Usb Ports | 1 | | Wireless Compability | Bluetooth | ## Product Details - **Brand:** DollaTek - **CPU model:** Core M Family - **Installed RAM memory size:** 0.01 GB - **Memory storage capacity:** 8 MB - **Model name:** DollaTek Voice Sound Playback Module ## Images ![DollaTek Voice Sound Playback Module Arduino MP3 Player Module UART I/O Trigger Class D Amplifier Board 5W 8M Storage SD/TF Card - Image 1](https://m.media-amazon.com/images/I/61DTjSVvJtL.jpg) ![DollaTek Voice Sound Playback Module Arduino MP3 Player Module UART I/O Trigger Class D Amplifier Board 5W 8M Storage SD/TF Card - Image 2](https://m.media-amazon.com/images/I/61g1MnIXBVL.jpg) ![DollaTek Voice Sound Playback Module Arduino MP3 Player Module UART I/O Trigger Class D Amplifier Board 5W 8M Storage SD/TF Card - Image 3](https://m.media-amazon.com/images/I/61F8Ze-SpvL.jpg) ![DollaTek Voice Sound Playback Module Arduino MP3 Player Module UART I/O Trigger Class D Amplifier Board 5W 8M Storage SD/TF Card - Image 4](https://m.media-amazon.com/images/I/61KZYbRvaFL.jpg) ![DollaTek Voice Sound Playback Module Arduino MP3 Player Module UART I/O Trigger Class D Amplifier Board 5W 8M Storage SD/TF Card - Image 5](https://m.media-amazon.com/images/I/61ItG2TyUyL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by N***. on 23 January 2026* Davvero semplice da usare, si caricano i wav o mp3 numerati, come fosse una chiavetta (per quanto lentissima) e poi, nella modalità base, basta portare i pin a ground e parte il suono.
