Bluetooth Amplifier Module.

A Bluetooth amplifier is a device that can receive audio signals from other devices via its built-in Bluetooth capability. It then amplifies those signals to be played out of speakers connected to the amp.

This Bluetooth board uses the TPA3110 amplifier IC while using a single power supply with an anti-reverse function. Power can be used with adapters and switching power supplies. This module includes a volume control potentiometer for when you need to turn up the volume or turn down the volume on the module.
