Hw-044 Datasheet ((better))

The HW-044 is a compact RS232 to TTL Serial Port Converter module. It acts as a bridge, allowing modern microcontrollers (like Arduino or ESP32) to communicate with legacy industrial equipment or computers that use high-voltage RS232 signals. Core Technical Specifications The module is built around the MAX3232 transceiver IC:

Introduction

Common Applications for the HW-044

Thanks to its robust datasheet-level performance, the HW-044 appears in countless projects: hw-044 datasheet

Form Factor: The HW-044 is preferred over the older MAX232-based modules because it requires fewer and smaller external capacitors (usually 4 x 0.1 μF) and supports lower voltages. Pros: The HW-044 is a compact RS232 to TTL
