3W Mini Audio Stereo Amplifier (W2)

This Mini Audio Stereo Amplifier from DFRobot transforms your audio experience with its powerful left and right channels, bringing stereo surround sound to any device you embed it into. Thanks to its compact design and 2mm pin pitch, installation is a breeze, seamlessly integrating into your projects without taking up much space. Coupling it with a Stereo Enclosed Speaker (FIT0502) allows you to directly control the audio amplifier without any need for programming, acting like a plug-and-play solution for crisp audio output.

This versatile amplifier offers sleeping and working modes to optimize power consumption. When you set pin "SW" to Low (0V), it intuitively switches to sleep mode by shutting down the bias circuit, effectively conserving energy. Conversely, setting pin "SW" to High (5V) activates working mode, ensuring you get uninterrupted performance. Conveniently, it starts in working mode by default when the pin is left unconnected, always ready to amplify your soundscapes.

Perfect for applications in robot voice systems, DIY music boxes, or sound modifications, this amplifier is an essential element in creating intricate audio projects. Its optimal performance requires careful attention to the polarity of connections, as mismatched positive and negative poles may result in malfunction. Additionally, ensure that the power supply does not exceed 5.5V to prevent damage to the IC, maintaining the integrity of your setup.
