Description
| MP3 player module, made for jobs that call for a small footprint and playback that needs no external player. Running on a supply between 3.7 V and 5 V DC, it has a built-in 2 W mono amplifier (up to 3 W on a 5 V supply), able to drive small speakers directly. Track playback (except in single-track loop mode) starts on its own as soon as power is applied.
It works with files in MP3 format and plays from USB drives (tested up to 32 GB) and TF/microSD cards (tested up to 16 GB). The on-board buttons handle track change (forward/back) and the choice of playback mode (single track or continuous repeat). Media selection is automatic: whichever memory device is plugged in (micro SD or USB stick) is detected. Its compact size (45.72 × 35.14 × 12 mm) and light weight (11 g) suit it to DIY projects, portable devices, voice or custom-message alarm systems, sound toys and built-in voice players. |
