This is a mini stereo amplifier breakout board. It is a fully functional, 3W two-channel audio amplifier.
Why be satisfied with a little buzzer when you can go stereo
Power Supply: DC 3.6-5.5V (DO NOT apply more than 5.5V, it will damage the chip)
Output power: 3w+3w (4 ohms)
Here is a simple wiring diagram, you could also integrate it with our FM Stereo Radio Module or simply use it as a cell phone amplifier.
We would recommend a 8 Ohm 1watt Mini Loudspeaker on each channel for practical uses.
