Description

MP3/WAV Audio Module, a compact and versatile solution for all your projects that need a sound output of high quality. This module is not just a simple music player; it is a real beating heart for any application that calls for voice messages or sound effects, from industrial installations to security systems, from access control devices to automated car parks.

Thanks to its 4MB built-in memory, you have plenty of room to load your audio files in MP3 or WAV format through the handy micro USB connection, which makes updating the content child’s play straight from your PC. Compatibility with Arduino UNO and other devices with a serial port opens up a world of possibilities for use in DIY and professional projects, with straightforward control both over the serial link and through analogue inputs.

The module is designed for efficiency and flexibility: power it with a voltage from 3.6 to 5.2 VDC and connect an 8 ohm 3 watt loudspeaker to enjoy powerful, clear sound. With five easily configurable buttons you have full control over volume, playback and track selection. Despite its small size (26×19.5×5 mm), this little gem does not compromise on audio quality, giving faithful playback from 8 to 320kbps.

A 10-way male pin strip connector is to be added so the module can be plugged into a board.
