Mini audio amplifier with Bluetooth

This audio power amplifier board can be used for a wide range of applications despite its small size and ease of use. It can amplify the recording of inaudible electronic audio signals with low power consumption to a level strong enough to be played back with speakers or headphones. A speaker impedance of 4 to 8 ohms can be used, making it easy to convert standard speakers into Bluetooth speakers. The board can also be used to receive the signal from radio receivers or electric guitars.

Bluetooth 4.0 is supported as an input and power is supplied via a micro USB connection.
