AA-AB41136 is a Bluetooth receiver board with Bluetooth V5.0, supporting various audio format as aptX, aptX HD, aptX LL, SBC and AAC. High performance DAC ensures high quality audio transmission. Terminal interfaces mounted for analog output make it easy for integration with audio amplifiers. In addition to Bluetooth receiver board, AA-AB41136 can work as a low power stereo audio amplifier, delivering 3W per channel into a 4Ohm load, quite suitable for bookshelf amplifier, desktop audio, garden audio, hotel audio and DIY applications that needs wireless audio connection. A DC5V-21V power supply is required.
Integrated with Bluetooth V5.0
AA-AB41136 employs Bluetooth 5.0 module for audio input, which supports various audio formats and high receive sensitivity with RF power up to 9dBm and -90dBm. There is a built-in antenna equipped on this board. An external antenna port is also provided on the board to ensure the stable connection and high audio performance even if this BRB3 is installed into a speaker or a cabinet. We have tested in open space with no interference, the Bluetooth wireless range can reach up to 80m. When input with maximum volume, the max line output voltage is 0.9Vrms. BRB3 supports Bluetooth name customization as well.
Low Power Stereo Audio Amplifier
This Bluetooth receiver board – BRB3 can also work as a stereo low power audio amplifier, outputting 3W per channel. That means, you can directly connect BRB3 with speakers for audio playback. Low power and wireless audio connection make BRB3 rather applicable to portable speakers, hotel audio, desktop audio and DIY applications.
High Quality Audio Performance
Thanks to carefully selected Bluetooth 5.0 module and engineers’ dedicated test and debug, BRB3 provides extremely high quality audio performance, which can definitely meet your Hi-Fi requirements.
Supporting Battery Power
Apart from power supply, BRB3 supports battery power, which further improves the portability of the audio system. It is recommended to use WONDOM BCPB series (battery boards with charging circuit) to power BRB3 as there is no charging circuit equipped on BRB3.
Low Power Consumption and Long Playback Time
BRB3 features low power consumption and high efficiency. You can enjoy music for long time even if you are outside and power it with a battery board. The quiescent current of the whole BRB3 board is 10mA. When the music is stopped, the power output stage would shutdown automatically to reduce power consumption.
Easy for Integration and Control
BRB3 is in compact size as 3’’ x 2’’, which means that it can be installed into any audio project without worry about occupying too much space. Four screw holes are offered for easy installation and immobilization. All the necessary connectors for normal connection and playback are provided on the board, therefore, you just need to plug in cables and enjoy music. Bluetooth pairing cancellation function is equipped on BRB3 for simple control.
Functional Cables Kit Optional
Taking convenient integration into account, we prepare a functional cables kit for BRB3, which includes 1pc Bluetooth antenna, 1pc Bluetooth pairing cancellation cable with button, 1pc 3.5mm line output cable, 1pc PH-4pin cable, 1pc speaker output cable and 1pc Bluetooth LED indicator cable. As for details, please refer to Functional Cables Kit for BRB3 (AA-AA11435).
