Description

The XY‑WRBT Bluetooth 5.0 Audio Receiver Board is a high‑quality stereo audio decoding module. I use it to upgrade wired amplifiers bring life to old stereos or make my own DIY Bluetooth speakers. The XY‑WRBT uses Bluetooth 5.0 giving me latency and a steady signal even at 15 meters. The background noise stays very low.

Because the XY‑WRBT operates from 3.7V up, to 24V DC I can power it in ways. I can plug a Micro‑USB cable in I can use a single 3.7V lithium battery or I can connect it straight to an amplifier that has a 12V or 24V power rail.

Key Features

Wide Voltage Compatibility: Power the board using a 5V Micro-USB cable, a 3.7V Li-ion battery or a DC source up to 24V. No step-down buck converter is needed.
Dual Output Options: Connect audio systems through the standard onboard 3.5mm stereo jack or solder directly to the rear stereo pads (L, G, R).
Automatic Reconnection: The board automatically reconnects to the paired device as soon as it powers on.
LED Status Indicator: A blue LED on the board flashes quickly when, in pairing mode stays solid when connected and pulses slowly during music playback.
