Fermion 3W Mini Audio Stereo Amplifier

This 3W Mini Audio Stereo Amplifier from DFRobot has a left and right channel, allowing you to achieve stereo surround sound. The module is compact and has a hole spacing of 2.54mm, to which you can solder pin headers or wires directly. The Mini Audio Stereo Amplifier has two modes: sleep and work mode. When the pin "SW" is low (0V), the amplifier goes into standby mode, while at pin "SW" high (5V) the operating mode is activated. The audio stereo amplifier is in work mode by default (the pin is not connected). 

This Mini Audio Stereo Amplifier can be used in robot voice systems, DIY game devices and sound modifications. 

Important Information:

1. The positive and negative poles must not be swapped. 
2. The negative poles for the left and right channels are independent of each other and must not be connected together. 
3. The power supply should not exceed 5.5V. A voltage that is too high will damage the IC.
