Usdrwam 6PCS Max98357A I2S Audio Amplifier Modules, 3W Class D Dac

Package & uses: 6-pack modules plus 1 male-to-female and 1 female-to-female Dupont jumper. Ideal for ideal for DIY speakers, digital assistants, portable audio, robotics, classroom electronics, prototypes and multi-channel deployments. Recommended for programming and rapid prototyping with compatible with modern development tools, Note: Outputs are bridge-tied PWM ( 300 kHz) and are designed to drive speakers directly - not intended to be tied the outputs to ground or feed them into another amplifier. Recommended speaker impedance: 4-8. Output power (5 V, 10% THD): 3.2 W at 4, 1.8 sustained high-power use ensure good ventilation or add a heatsink, and use a stable power supply to minimize noise, Formats & gain: Supports I2S/12S/LJ/TDM with sample rates 8-96 kHz and no external MCLK; gain selectable via the GAIN pin (3 / 6 / 9 / 12 / 15 dB, default 9 dB) and SD/MODE selects shutdown or left/right (default L+R mono mix). Compact yet powerful-achieves AB-class like audio performance at Class-D efficiency, delivering up to 3.2 W of clear and detailed audio output for a wide range of applications, Plug and Play: Compact WLP design reduces parts and PCB size; digital input improves noise immunity and ~8 dB jitter tolerance with improved jitter tolerance (~8 dB); built-in EMI suppression supports longer speaker runs without extra filtering - high-quality sound with minimal components and efficient Class-D performance, DIY & Maker Friendly: Ideal for hobbyists, students, and developers creating custom audio projects. Works seamlessly with Arduino, Raspberry Pi, ESP32 and other MCUs. Perfect for portable speakers, 3D-printed enclosures, and wearable devices. Includes Dupont cables for easy. Compact design with digital input delivers reliable Class-D performance for DIY audio and learning projects.
