Bluetooth 5.0 Audio Receiver Board - Controllable Volume

This Bluetooth 5.0 Audio Receiver module is designed to effortlessly transform your ordinary loudspeaker into a wireless marvel. With its small size and cost-effective design, it functions seamlessly within a wide-range power supply from 3.7V to 24V. Equipped with a function button, it makes controlling audio playback convenient. Dial the button to adjust the volume, or press it to pause and play, integrating tactile simplicity into technological sophistication.

Once powered on, the module quickly enters Bluetooth mode with a rapid blue indicator flash. An auditory prompt signals its readiness for pairing. Simply activate Bluetooth on your device, locate “XY-WRBT” in your device list, and connect. A successful connection is confirmed by another audio prompt, allowing you to play your music while the indicator blinks rhythmically. This intuitive connection process bridges the gap between your device and any speaker, rendering a wired future obsolete.

This module carries a few operational notes. If the power supply dips below 3.3V, the board will switch off automatically, ensuring protection for your equipment. A new battery or a simple contact short-circuit can relaunch its functionality. Low voltage might introduce noise, acting as a prelude to recharging. A Lipo Charger board is recommended for optimum use due to the absence of a lithium battery protection circuit. Additionally, ensure electrostatic protection as the sensitive Bluetooth chip could be damaged by static electricity. Maintain distance from radio transmitters and metal objects to preserve signal clarity.
