Wireless Stereo Bluetooth V2.1+EDR Audio Receiver Board Amplifier Sound Module
Features:
- This Bluetooth digital amplifier board， use the Bluetooth core BEKEN high quality music and compatibility Bluetooth chip， built-in enhanced signal transmission circuit， Bluetooth receiver from the stable continuous sound， built-AEC echo cancellation and noise cancellation ANC circuit， speakerphone ultra-quiet no response and noise. amplifier IC enables efficient M6008N pure class D chip. With ultra-wide bandwidth excellent EMI performance Low-E， the maximum power output 5Wx2， with USB / 5V-powered push 3W or 5W speakers， powerful bass output pure treble clear， beautiful appearance， stable， sound quality is excellent， the price of real distinctions.
Amplifier chip features:
- 1. with anti-breaking sound control function， can detect and suppress the input music， voice signal amplitude is too large output signal caused by broken sound and minimizes distortion and noise pulse output signal.
- 2. chip built-in shutdown function enables standby current is minimized， also integrates mute function， fade effect， the speaker output over-current protection， over-temperature protection inside the chip and other features.
- 3. function switch， a voice prompt
- 4. Powered using the USB interface， Bluetooth stereo dual speaker outputs， paired with a Bluetooth phone or computer， can wirelessly listen to music， but also hands-free phone calls， back-linking function. Support TF card play， outside LINE IN input， automatic switching function. (3.5mm stereo headphone plug audio signal input do have audio amplifiers).

Note:
- 1.Power supply voltage can not exceed 5.5V
- 2.Chip supply voltage can not be lower than 1.8V， if low 1.8V， undervoltage protection function automatically start to prevent the chip logic disorder due to burning amplifier tube. After starting the undervoltage protection mode， the supply voltage if the direct return 5V， the chip is still in the protection of the state， to prevent chip damage to repeatedly switch at low voltage.
