Bluetooth 5.0 decoder board for audio projects

This module adds Bluetooth 5.0 wireless streaming, FM radio reception and local file playback to DIY audio builds. It accepts TF cards and USB storage for MP3 or APE files and provides an auxiliary input for wired sources. Makers and hobbyists integrating sound into custom enclosures will find the feature set convenient.

Simple 5 V wiring with attention to shared ground

Power the board from a stable 5 V supply and connect the audio output to an amplifier or powered speakers using the provided pins. Common issues include ground loops that cause hum when the same supply feeds both the board and the amplifier, and intermittent TF card detection if the card is not fully seated or formatted to a compatible filesystem. Ensure the antenna wire is extended for reliable FM reception.

How do I confirm the Bluetooth 5.0 module is working after wiring it up?

Pair a phone to the board, play audio through the AUX or speaker outputs, and verify sound comes through without drops.

What comes in the box and what must I source separately for the 5 V decoder board?

The board itself is supplied; you will need to provide a 5 V power source, speakers or headphones, and any TF card or USB drive for media playback.
