The DIY Bluetooth 5.0 Audio Receiver Module is a compact, versatile wireless audio solution designed for car stereo upgrades, home speaker systems, and custom amplifier projects. It combines Bluetooth 5.0 connectivity, MP3 decoding, and ABT (Audio Broadcasting Technology) support into a single, easy-to-integrate board, making it an ideal choice for DIY enthusiasts, makers, and product developers.
At its core, the module features a Bluetooth 5.0 chipset that supports A2DP, AVRCP, and HFP protocols, enabling stable wireless audio streaming from smartphones, tablets, and computers up to 10 meters away. The board also supports ABT (Audio Broadcasting Technology) , allowing for extended-range audio transmission in compatible systems.
The module includes MP3 decoding capability, supporting playback of MP3 files from USB drives or TF cards. This makes it a standalone audio solution — you can play music directly from a USB flash drive or memory card without needing a Bluetooth connection. The board also supports lossless audio formats for high-quality playback.
For integration, the module provides line-level stereo output that connects directly to car stereo AUX inputs, home amplifier inputs, or powered speakers. An onboard 3.5mm audio jack simplifies connection to external amplifiers, while screw terminals provide secure wiring options for permanent installations.
The board is powered by a DC 5V supply via a Micro USB or Type-C connector (variant dependent), making it compatible with USB power adapters, power banks, and car USB ports. The compact form factor, measuring approximately 50 × 30 mm, allows it to fit into tight spaces behind dashboards, inside speaker enclosures, or within custom project boxes.
Whether you are upgrading a vintage car stereo, building a portable Bluetooth speaker, or adding wireless audio to a home hi-fi system, this DIY Bluetooth 5.0 Audio Receiver Module provides a practical, cost-effective foundation. It is suitable for individual makers, students, and businesses purchasing in bulk for product development or educational programs.
