Bluetooth Power Amplifier Board 2x5W Dual Power Output DIY Bluetooth 5.0 Stereo Receiver Module

1. [Button Control and Bluetooth 5.0 Chip] With button control, there are controls for up and down songs, volume addition and subtraction, play, pause, switch machine, etc. Using Bluetooth 5.0 main control chip, good transmission effect and high stability.

2. [Micro 5p Interface Powered] Powered by micro 5p interface, ordinary mobile phone charger 5V2A charging cable can be used. (recommended 5V/3A, if 5V/2A power supply is used, it is recommended to play more power in class D mode of 5V/3A Large).

3. [Output interface and Installation] Output interface: 3.5mm stereo (reserved welding port, you can DIY). Installation: When installing the Bluetooth board, the Bluetooth antenna should not be close to the metal parts as much as possible, so as not to affect the transmission distance.

4. [Practical Use] The Bluetooth signal of phone, laptop, and tablet can be transmitted to power amplifier, active speaker and other device. The interface can also be connected to 3.5mm headphones to turn into Bluetooth headphones. (without mic, voice chat is not supported).

5. [Dual Power Output] Speaker output ports 2 groups (one for each left and right channel) cannot be used with the headphone plug at the same time. When the headphone plug is connected to the headphone, the device will auto switch to the headphone output, and at the same time stop the signal of the speaker output port of the power amplifier board.
