Bluetooth Stereo Amplifier Module - 2x 3W speaker - Kitronik 2182

Bluetooth Stereo Amplifier Module is a modern amplifier for prototype projects that enables remote and direct music playback using a phone, tablet or computer. It uses Bluetooth wireless communication and enters pairing mode after the first start - it is automatically detected by a nearby device and is displayed under the name R001. The set also includes two 67 x 67 mm speakers with an impedance of 4 Ohm and a power of 3 W each. Both the amplifier board and the speakers have mounting holes through which the whole can be mounted in specially designed housings.

Once powered on, the board enters pairing mode and is discoverable by nearby compatible devices.
