Adopting Bluetooth 5.0 technology, it provides longer transmission distance, higher transmission speed, and lower power consumption. <br />2. Supports stereo output: Supports high-quality stereo audio decoding, providing clear and delicate sound quality experience. <br />3. Low latency transmission, optimized audio transmission algorithm ensures low latency of audio transmission, especially suitable for scenarios that require audio and video synchronization such as watching videos and playing games. <br />4. Multiple interfaces, including 3.5mm audio interface and TYPE-C power supply interface, facilitate the connection of different audio devices such as headphones, speakers, sound systems, etc. <br />5. The module has a protection mechanism that supports reverse power protection.</p> <p>Product Description: <br />After connecting the power, the blue indicator light flashes rapidly and enters Bluetooth mode; After broadcasting the "prompt sound", enter pairing mode and wait for pairing; Search for "XY-WRBT" (amplifier board device name) on the Bluetooth of your mobile phone, click on "XY-WRBT" to connect, and after successful connection, play a "prompt sound" with the indicator light on continuously to play music on your phone. When playing music, the indicator light flashes slowly; After disconnecting Bluetooth, the power amplifier board prepares for the next pairing and plays a "prompt sound" before entering pairing mode and waiting for pairing.</p> <p>Parameter: <br />Product Name: Bluetooth Decoding Board <br />Working voltage: 3.7~24VDC <br />Bluetooth version: 5.0 <br />Transmission distance: 15 meters (visible without obstruction) <br />Signal to noise ratio: &ge; 90dB <br />Distortion: &le; -70dB <br />Number of channels: Dual channel (stereo) <br />Audio interface: 3.5mm audio interface <br />Module protection mechanism: reverse power protection <br />1. The power supply can use Micro USB/TYPE-C USB mobile phone charger, 3.7-4.2V lithium battery, 3.7-24V DC power supply, choose one of the three. <br />2. Short circuit the "on/off contact" for 2 seconds to set the decoding board on/off. For battery powered situations, shutting down when not in use is more energy-efficient and convenient for modification. <br />Precautions for using 3.7V lithium battery power supply <br />When using battery power, if the battery voltage is lower than 3.3V, the decoding board will automatically shut down. After re powering on or fully charging, short circuit the on/off contacts for 2 seconds to turn on. <br />When using battery power, if the battery voltage is too low, there may be "sizzling" noise, in which case the battery needs to be charged. <br />3. As there is no lithium battery charging protection circuit designed on the decoding board, it is recommended to use lithium batteries with built-in protection boards. <br />If your rechargeable battery supports MicroUSB direct charging, you can use Micro USB/TYPE-C USB to directly charge the battery.</p> <p>TPackage include: <br />Audio module x1<br /></p></div></div>
