Hw-044 Datasheet Site

If you are not receiving data, try swapping the TXD and RXD connections on the TTL side. 3. How to Use the HW-044 Module with Arduino

The is a versatile, compact, and affordable module that solves two common problems in mixed-voltage electronics: generating a clean 3.3V rail and translating logic signals between 5V and 3.3V systems. While it lacks an official, unified datasheet, the information provided in this guide—derived from its constituent components and empirical testing—serves as a reliable technical reference. hw-044 datasheet

If you wish to incorporate the HW-044’s functionality into your own product, refer to this minimalist schematic: If you are not receiving data, try swapping

The most critical section of the HW-044 datasheet for the builder is the pinout. Unlike many sensors that require 4 pins (VCC, GND, and data), the HW-044 typically uses a . While it lacks an official, unified datasheet, the
