Choose HW-044 when you have a digital audio source (SD card, internet stream, codec) and want the cleanest audio without analog interference.
The HW-044 is a compact, pre-assembled module designed to drive common-cathode LED displays. Its core component is the integrated circuit from Maxim Integrated (now Analog Devices). The module allows microcontrollers (e.g., Arduino, ESP32, STM32) to control up to 64 individual LEDs (8 digits of 7-segments plus decimal points, or an 8x8 dot matrix) using only three I/O pins .
