MAX98357 I2S Audio Amplifier Module, 3W Class D Filterless Decoder Board with MAX98357A Chip

High Fidelity Sound in a Compact Module This audio power amplifier module is built around the MAX98357A chip and delivers a powerful 3W output through its Class D architecture. Despite its small footprint, the board produces clear, detailed audio with minimal distortion, making it well suited to audio engineering work, hobbyist projects and any application where faithful sound reproduction matters. The filterless design keeps the circuit simple and efficient while maintaining excellent audio quality. Flexible Gain Control for Your Project The module offers selectable gain settings of 3 dB, 6 dB, 9 dB, 12 dB and 15 dB, so you can match the amplification level precisely to your requirements. Whether you are assembling a home speaker system, adding sound to a robotics project or developing professional audio equipment, this adjustability gives you practical control over the output without additional components. Clean Audio in Demanding Environments Digital inputs with strong jitter tolerance and effective noise suppression help keep the signal clean, even in electronically busy settings. The circuitry is designed to reject interference, so your audio remains clear and undistorted when the module is used alongside other electronic components. Straightforward Integration with Common Platforms The board supports automatic configuration across 35 clock sources and 128 digital audio formats, which simplifies integration into a wide range of systems. The I2S sampling rate spans 8kHz to 96kHz, covering most standard audio requirements. It works well with Raspberry Pi projects and other microcontroller-based builds that need quality audio output. Please note that this module is supplied unwelded, so the pins will need to be soldered before use.
