Need a simple, affordable way to play MP3s in your DIY project?

This decoder board is a great little module.

It supports MP3 format files from a TF card (microSD) or a USB flash drive (tested up to 32GB and 16GB respectively).

It has a built-in 2W mono amplifier that can connect directly to a 4-ohm, 3-watt speaker, plus a 3.5mm gold-plated headphone jack for private listening.

Power it via the micro USB port (5V) or a 3.7V lithium battery—super flexible.

The board has buttons for play/pause, volume, track skipping, and mode switching.

When it plays, a red LED flashes.

It powers on automatically and starts playing.

There's no soldering needed for the speaker terminals, which makes wiring easy.

It's an assembled and tested module, so you can get it up and running quickly.

Perfect for custom audio projects, jukeboxes, or just experimenting.
