DFRobot Fermion 3W Mini Audio Stereo Amplifier

This 3W Mini Audio Stereo Amplifier from DFRobot features a left and right channel, allowing you to achieve stereo surround sound. The module is very compact and has a pin spacing of 2.54 mm, to which you can directly solder pin headers or wires. The mini audio stereo amplifier has two modes: sleep mode and working mode. When the "SW" pin is low (0V), the amplifier enters sleep mode, while a high (5V) on the "SW" pin activates the working mode. By default, the audio stereo amplifier is in working mode (the pin is not connected).

This mini audio stereo amplifier can be used in robot voice systems, DIY gaming devices, and sound modifications.

Important information:
The positive and negative terminals must not be reversed.
The negative terminals for the left and right channels are independent and must not be connected together.
The power supply should not exceed 5.5V. Excessive voltage can damage the IC.
