3PCS MAX98357 I2S Audio Amplifier Module, Class D Filterless Power Amplifier Board with 3W Output, Compatible with Arduino Raspberry Pi ESP32 DIY Audio Projects

• High-Performance MAX98357 I2S Class D Audio Amplifier – This 3W mono amplifier module features the MAX98357 DAC with filterless architecture, delivering clean, low-distortion audio from I2S digital input. It automatically supports up to 35 clock rates and 128 audio data formats with single-supply operation (2.7V–5.5V), making integration seamless for DIY audio upgrades.
• Plug-and-Play Sound Solution for Makers – No external filters or complex PCB layouts required. The board offers excellent electromagnetic interference (EMI) suppression and high jitter tolerance, allowing long speaker wires without noise pickup. Simple 3‑wire connection (BCK, LRCK, DIN) enables quick setup with any I2S‑capable host.
• Dramatic Audio Quality Improvement – Replace low‑fidelity PWM or analog outputs with crisp, high‑dynamic‑range I2S sound. This module effectively eliminates background hiss and digital artifacts, providing clear, enjoyable audio for voice prompts, music playback, and alert tones. Adjustable gain (e.g., 3 dB setting) lets you fine‑tune output for different speaker impedances.
• Wide Compatibility with Popular Development Boards – Designed for microcontrollers and SBCs that support I2S output, including Arduino, Raspberry Pi, ESP32, ESP8266, and many other ARM‑based platforms. The 3‑pack value set is ideal for multi‑channel systems or multiple project builds.
• Versatile Application Scenarios – Perfect for portable Bluetooth speakers, smart home voice interfaces, IoT notification devices, retro game console audio, and wearable sound projects. Lightweight and compact, this module adds high‑quality audio capability to any maker or prototyping environment.
