Description
The VHM-314 Pro Bluetooth 5.0 MP3 Decoder Board offers a simple yet powerful solution for transforming wired audio systems into modern, wireless setups. This “Pro” or “Deluxe” version differentiates itself from the standard model by including a built-in microphone and sometimes onboard control buttons, enabling hands-free calling functionality in applications like car audio systems. Utilizing the latest Bluetooth 5.0 technology, this module ensures a stable connection, faster transmission speeds, and high-fidelity, lossless audio reception (supporting formats like WAV, APE, FLAC, and MP3).
This board acts primarily as an audio receiver and decoder; it does not include an integrated power amplifier, meaning it must be connected to an external amplifier or active speakers for sound output. Its compact size and simple 3-wire connection (Power+, Power-, and Audio Out) make it perfect for discreet installations in car stereos, home theater systems, or custom-built speakers. The board operates on a flexible power input range of 3.7V to 5V DC, suitable for standard USB power supplies (via Micro USB or Type-C port) or portable battery setups.
