Description:
This is an audio power amplifier board that strengthens low-power, inaudible electronic audio signals such as the signal from radio receiver or electric guitar pickup to a level that is strong enough for driving loudspeakers or headphones. Power amplifiers make the signal audible to listeners. It is the final electronic stage in a typical audio playback chain before the signal is sent to the loudspeakers and speaker enclosures.

Features:
Digital amplifier has a higher overload capacity than analog amplifier, and it won't cause crossover distortion, transient inter modulation distortion and you don't have to worry about the loudspeaker internal resistance.
It supports Bluetooth audio input and DC 5V voltage input by Micro USB.
Dual channel of 3W+3W power output and 2.54mm, 4pin output connector.
Sound quality is very good by using this audio power amplifier module.

Applicable speaker impedance are 4~8ohm, great for turning normal speaker into Bluetooth speaker.
