7V-30V Bluetooth 4.0 Audio Receiver Board Wireless Stereo Sound Module
Wide voltage conversion module Bluetooth 7V-30V with anti-reverse design allows DIY with ease.
Bluetooth module output op amp with NE5532 pre-amplified output signal amplitude, promote common amplifier board without pressure.
Audio signals with automatic switching function, can guarantee the original amplifier or powered speakers to increase functional status under the Bluetooth function, the implementation of lossless conversion.
Using picture-board design, up to 4 shelves full effect SMT precision industrial processing.
Then the power output of the output signal can work automatically, Bluetooth priority.
Power :7-30v wide voltage operation.
PCB board size: 50x60MM
Or 4.0 Bluetooth V2.0/3.0
Effective trans distance: about 10 meters (dependant on environmental obstacles)
Can not be directly connected to speakers.
Supports an external Bluetooth antenna. External buttons can be accessed by you can not answer "Note: Bluetooth antenna and keys, once soldered no return or exchange accepted."
Bluetooth receiver board that not all computers can be paired with
Wiring and instructions steps:
Wide voltage operating range, with anti receiver design, supply 7-30VDC
Automatic power regulator, then the receiver display a blinking blue light, it's better if a direct connection can be automatically connected
Open the phone or other Bluetooth devices such as laptops, tablet computers, mobile phone as an example: open its Bluetooth function, the phone will automatically search, automatic pairing with its modules, most mobile phones do not need to enter the key, the individual parts of the phone such as 0000 need to enter key will display the module name M-DIY is connected on the phone after the connection is successful,
Audio input module audio output jacks audio equipment, or access to the audio input amplifier board, and you're done! Enjoy your own DIY wireless amplifier it! ! Input interface can be connected to another source, when the Bluetooth stops working, it will automatically switch to another source
After the pairing is successful, the function keys on the module, down song, and volume addition and subtraction, pause can use!
