Hw-044 Datasheet Best Jun 2026

I hope this example paper helps! Let me know if you have any specific requests or need further modifications.

Converts high-voltage RS232 levels to logic levels and vice versa. hw-044 datasheet

The HW-044 simplifies driving multi-digit LED displays or matrices by reducing I/O pin usage. Its built-in MAX7219 handles multiplexing, current control, and memory refresh. With a simple 3-pin serial interface, it is ideal for microcontroller projects requiring visual output without complex wiring or real-time software multiplexing. I hope this example paper helps

ESP32 ADC is non-linear near the rails. The HW-044 at 3.3V works well, but expect reduced total range (~0.2V to 3.1V). hw-044 datasheet
