DFRobot Bluetooth 5.0 Audio Receiver Board
The Bluetooth 5.0 Audio Receiver Board is a compact and cost-effective solution for adding wireless capabilities to your existing speakers. This versatile Bluetooth audio receiver allows you to easily transform any old speaker system into a modern wireless setup without complicated wiring or expensive replacements.
The module features the latest Bluetooth 5.0 technology, ensuring stable connections and quality audio transmission up to 15 meters in visible range. With its automatic reconnect function, you won't need to repeatedly pair your devices - once connected, the module remembers your device for future use. The board can be powered either through a micro-USB connection or a 3.7V lithium battery, giving you flexibility in how you install and use this wireless speaker converter.
What makes this Bluetooth 5.0 adapter particularly valuable is its dual functionality. Beyond serving as a wireless audio receiver, it can also function as a computer sound card.
By simply short-circuiting the Sound Card pads on the back of the module and connecting it to a computer via USB cable, you can use it as a USB sound card module - perfect for computers with damaged audio outputs or for adding an extra audio interface.
The operation is straightforward: after powering on, the blue indicator flashes as the module enters Bluetooth mode and plays an audio prompt while waiting for pairing. Your phone will detect the module as "BT5.0-Audio," and once connected, the indicator remains solid when idle and blinks slowly during music playback.
