Bluetooth 4.2 Audio Receiver Board-with an Amplifier (2x5W)

This compact Bluetooth 4.2 Audio Receiver module is ingeniously designed to incorporate dual 5W power amplifier circuits, rendering it a cost-effective choice for transforming ordinary speakers into a stereo Bluetooth system. With a straightforward connection via micro USB or a 3.7V lithium battery, the module ensures seamless audio experiences by supporting auto-reconnect, making it a reliable choice for continuous music streaming.

Engineered for effortless usability, the module enters Bluetooth mode with a swift blink of its blue indicator upon powering up. It quickly transitions into pairing mode, ready to connect with devices. Once paired, your phone's “MH-M38” connection allows you to stream music effortlessly, while the steady indicator confirms an active connection, and gently pulses when music is live, enabling a dynamic audio adventure.

To ensure optimal functionality, it is recommended to integrate this module with a Lipo Charger board, as it does not feature a lithium battery protection circuit. Handle the module with care, discharging any static electricity from your hands to safeguard the sensitive Bluetooth chip. Additionally, place the module away from high-frequency or strong electromagnetic sources to preserve signal integrity and avoid interference.

The built-in dual 5W power amplifier circuits negate the need for external amplifiers, allowing you to fully leverage the module’s audio capabilities. Care must be taken not to connect the negative poles of the amplifier circuits, as doing so can harm the power amplifier chip, ensuring your audio setup remains both effective and secure.
