Hw-044 Datasheet May 2026

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.

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

void setup() Serial.begin(115200); WiFi.begin("SSID", "PASSWORD"); while (WiFi.status() != WL_CONNECTED) delay(1000);

Then use aplay or mpg123 to output audio directly. Despite its simplicity, users frequently encounter problems with the HW-044. Here is a debugging table based on real forums and datasheet analysis. The is a highly popular, inexpensive, and versatile
