High Accuracy MAX98357 I2S Amplifier Board Module for Raspberry Pi 2.7V-5V 3W
Features: 100% brand new and high quality
Class D amplifiers can operate at 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.
I2S audio input supports 3.3V and 5V levels. You can use the gain input to set the gain to the following values: 3dB, 6dB, 9dB, 12dB, and 15dB. By default, the stereo signal (L + R) is mixed to form the output signal. A resistor can be used to change the behavior so that only L or R is output.
It combines an I2S D/A converter and audio amplifier on one board. The small stereo amplifier module is powerful and can provide up to 3.2W of power on a 4Ω impedance speaker.
The I2S digital audio amplifier board is suitable for Raspberry Pi.Receive digital audio through the I2S interface, convert it into an analog output signal, and amplify it to achieve direct speaker connection.
The module was fully assembled and tested when it was delivered. The delivery includes a header and a 2-pin terminal
