Descrizione completa
Product Features:
1. Adopts Bluetooth 5.0 technology, providing longer transmission distance, higher transmission rate and lower power consumption.
2. Support stereo output: support high quality stereo audio decoding, provide clear and delicate sound quality experience.
3. Low Latency Transmission
Low Latency: Optimised audio transmission algorithm ensures low latency audio transmission, especially suitable for watching videos, playing games and other scenarios that require audio and video synchronisation. The delay time is usually within 20ms, almost imperceptible delay.
4. Multiple interfaces, 3.5mm audio interface and TYPE-C power supply interface, convenient for connecting different audio devices, such as headphones, speakers, sound systems, etc.
5. The module has a protection mechanism to support power reverse connection protection.
[Product Parameters]
Product Name: Bluetooth Decoding Board
Product Model: XY-WRBT
Working voltage: 3.7~24VDC
Bluetooth version: 5.0
Transmission distance: 15 meters (visible without obstruction)
Signal to noise ratio: ≥ 90dB
Distortion: ≤ -70dB
Number of channels: Dual channel (stereo)
Audio interface: 3.5mm audio interface
Module protection mechanism: power reverse connection protection
[Interface Description]
1. Power supply can be provided by using Micro USB mobile phone charger, 3.7-4.2V lithium battery, 3.7-24V DC power supply, or any one of the three.
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.
[Operation Instructions]
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 your phone's Bluetooth, click on "XY-WRBT" to connect. After successful connection, play a "prompt sound" and the indicator
light will stay on to play your phone's music. When playing music, the indicator light will flash 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.
Precautions for using 3.7V lithium battery power supply
1.When using battery power, if the battery voltage drops below 3.3V, the decoding board will automatically shut down and restart Short circuit
the on/off contacts for 2 seconds after charging or fully charging to turn on the device.
2.When using battery power, if the battery voltage is too low, there may be a "sizzling" noiseSound, in this case, the battery needs to be charged.
3. As there is no lithium battery charging protection circuit designed on the decoding board, it is recommended to use the built-in protection circuit
Lithium battery for protective plate.
4.If your rechargeable battery supports MicroUSB direct charging, you can use Micro USB directly charges the battery.
