SparkFun MAX98357A I2S Audio Breakout

The SparkFun I2S Audio Breakout Board uses the digital-analog converter (DAC) MAX98357A, which converts I2S audio (not to be confused with I2C) into an analog signal to drive speakers. The I2S Audio Breakout converts the digital audio signals according to the I2S standard into an analog signal and amplifies the signal with a Class-D amplifier, which can deliver up to 3.2W power to a 4Ω load. The breakout board can be configured to output only the left channel, the right channel, or both. The SparkFun I2S Audio Breakout Board is quite simple and only requires a few pin connections to get it running. By default, the board is configured in "Mono" mode, i.e. the left and right signal are combined to drive a single speaker. If you need a separate speaker for the left and right audio channel, you must sever the mono jumper. In addition to being able to select the audio channel output, the gain can also be configured in various ways. The gain of the amplifier can be configured as low as +3dB to as high as +15dB. While the channel selection can be configured on board, the gain, however, is controlled externally via the gain pin. By default, the board is configured for +9dB but can be easily changed!
