Accepts digital audio through the I2S interface, converts it to an analog output signal and amplifies it to allow direct speaker connection. It combines an I2S D \/ A converter with an audio amplifier on one board.\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003eThe small stereo amplifier module is surprisingly powerful and delivers up to 3.2W on 4Ω impedance speakers. The class D amplifier can be operated with a voltage of 2.7 V - 5.5 V. Due to the high efficiency of the amplifier, the module is particularly suitable for mobile and battery-powered projects.\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003eThe I2S audio input supports 3.3V and 5V levels.
