Bluetooth Stereo Audio Receiver Board 3.5V-5V – Mini Wireless MP3 Lossless Decoder Module for DIY Speakers

Overview

Bring wireless convenience to your audio setups with the Mini Bluetooth Stereo Audio Receiver Board. This high-fidelity module receives wireless audio signals from your smartphone, tablet, or laptop and outputs clear, dual-channel stereo sound. Thanks to its wide operating voltage range (3.5 V – 5 V), it can run directly from a single 3.7 V 18650 lithium battery or a standard 5 V micro-USB adapter. Its micro-sized footprint allows it to easily slip inside existing amplifier housings, headphone shells, or custom 3D-printed projects.

Key Features 

• Lossless Audio Streaming: Supports premium wireless decoding protocols for clean, crisp music streaming without distortion.

• Dual Power Routing: Can be powered via dedicated solder pads for portable battery setups or standard 5 V input lines.

• Automatic Reconnection: Once paired with your device, the module automatically re-establishes the connection every time it powers up.

• Status LED Indicator: Features an onboard blue LED (rapid blinking means waiting to pair, solid light indicates successful connection).

• Pre-Routed Audio Pins: Clear $L$ (Left Channel), $R$ (Right Channel), and $AGND$ (Audio Ground) pins make routing to your amplifier board instant and trouble-free.
