Datasheet: Hw-044

The HW-044 expects MSB-first , left-justified data with 1 BCLK delay after LRC transition (standard I²S). Do not invert BCLK or LRC unless your microcontroller driver specifically requires it. 7. Software Libraries & Code Examples To use the HW-044, you need a microcontroller that can generate I²S. Below are minimal examples for two popular platforms. 7.1 ESP32 with Arduino IDE #include <WiFi.h> #include <Audio.h> // I2S pins #define I2S_BCLK 26 #define I2S_LRC 25 #define I2S_DIN 22

Introduction

For 44.1 kHz / 16-bit stereo, BCLK = 44,100 × 16 × 2 = 1.4112 MHz. The HW-044 handles this easily. hw-044 datasheet

The is a highly popular, inexpensive, and versatile breakout board for the MAX98357 audio amplifier IC. If you are searching for the hw-044 datasheet , you are likely working on an embedded audio project involving an Arduino, ESP32, ESP8266, Raspberry Pi, or any other microcontroller that supports I²S (Inter-IC Sound) audio. The HW-044 expects MSB-first , left-justified data with
