The \u003cb data-path-to-node=\"7\" data-index-in-node=\"147\"\u003eMAX98357A I2S Audio Amplifier Module\u003c\/b\u003e is designed to take the digital audio straight from your microcontroller and drive a speaker directly. By keeping the audio strictly in the digital domain until the very last stage, it drastically reduces interference, static, and signal degradation, ensuring pristine sound quality for your projects.\u003c\/p\u003e\n\u003cp data-path-to-node=\"7\"\u003e \u003c\/p\u003e\n\u003ch3 data-path-to-node=\"8\"\u003eSeamless I2S Integration (No MCLK Required)\u003c\/h3\u003e\n\u003cp data-path-to-node=\"9\"\u003eOne of the biggest hurdles in digital audio is clock synchronization. This module simplifies your build by eliminating the need for a master clock (MCLK). It features an integrated PLL (Phase-Locked Loop) that automatically detects the BCLK and LRC frequencies, allowing it to seamlessly configure up to 35 different clocks and 128 digital audio formats. Simply connect the standard I2S pins (DIN, BCLK, LRC), provide power, and you are ready to play audio from your ESP32 or Raspberry Pi.\u003c\/p\u003e\n\u003cp data-path-to-node=\"9\"\u003e \u003c\/p\u003e\n\u003ch3 data-path-to-node=\"10\"\u003eCompact Size, Massive Output\u003c\/h3\u003e\n\u003cp data-path-to-node=\"11\"\u003eDon't let the small footprint fool you. Running on a standard 5V logic supply, this filterless Class D amplifier delivers a robust \u003cb data-path-to-node=\"11\" data-index-in-node=\"131\"\u003e3.2W of power into a 4Ω speaker\u003c\/b\u003e or \u003cb data-path-to-node=\"11\" data-index-in-node=\"166\"\u003e1.8W into an 8Ω speaker\u003c\/b\u003e. The high efficiency of the Class D architecture means it generates minimal heat, making it perfect for battery-powered or tightly enclosed portable audio projects.\u003c\/p\u003e\n\u003cp data-path-to-node=\"11\"\u003e \u003c\/p\u003e\n\u003ch3 data-path-to-node=\"12\"\u003eBuilt for Makers and Fast Prototyping\u003c\/h3\u003e\n\u003cp data-path-to-node=\"13\"\u003eTime is your most valuable asset when prototyping. We stock this module with the 7-pin header already pre-soldered, alongside a robust screw terminal for your speaker wires. Whether you are dropping it onto a breadboard for testing or wiring it permanently into a 3D-printed enclosure, it is designed for rapid deployment. Backed by Sun Cheong Computer's 20 years of trusted electronics supply, you can rely on this module for consistent, high-fidelity performance.\u003c\/p\u003e","brand":"Sun Cheong Computer Company Limited","offers":[{"title":"Default Title","offer_id":47720821588119,"sku":"21PS002633","price":25.0,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0440\/4022\/4919\/files\/max98357a-i2s-audio-amplifier-module-front.jpg?v=1777026105","url":"https:\/\/scccltd.com\/products\/max98357a-i2s-audio-amplifier-module","provider":"Sun Cheong Computer Company Limited","version":"1.0","type":"link"}
