The is a serial port converter module designed to bridge the gap between RS232 signals and TTL (Transistor-Transistor Logic) levels. It is built around the MAX3232 integrated circuit, which allows standard COM port signals (typically ±12Vplus or minus 12 cap V
Ensure the ground of the Arduino and the ground of the RS232 device are connected through the HW-044. 6. HW-044 Advantages
The HW-044 module features two distinct interfaces: a standard DB9 female port for the RS232 device and a 4-pin header for the microcontroller. TTL Interface (Microcontroller Side)
Yes. Connect the VCC to the Pi's 3.3V pin, GND to GND, TXD to the Pi's RX (pin 10), and RXD to the Pi's TX (pin 8). Do not connect VCC to 5V on a Raspberry Pi.
The ESP32 has native I²S support and is the most common companion for the HW-044.
Connects to the positive power input of your load/project circuit.
HW-044 Datasheet: Complete Pinout, Specifications, and Arduino Guide
On many Arduino boards, Pin 0 is RX and Pin 1 is TX. These pins are also used for USB communication via the onboard serial converter. To avoid conflicts when your code is uploading, it's best to disconnect the HW-044's TXD and RXD pins from pins 0 and 1 while uploading new code to the Arduino. You can reconnect them once the upload is complete.
Note: Standard Arduino Uno does not support I²S natively on all pins. Use an Arduino Due or Zero for best results, or a software bit-banging library.
The is a highly efficient, dual-channel RS232-to-TTL serial port converter board . It bridges the gap between old legacy computer serial ports (or industrial sensors) and modern microcontrollers like the Arduino, ESP32, or Raspberry Pi. At its core, the board features the Texas Instruments / Maxim Integrated MAX3232 transceiver IC , making it an essential peripheral for hardware hacking, industrial automation, and serial communication prototyping. 1. Technical Specifications Overview
The HW-044 datasheet provides a detailed pin configuration, which is essential for understanding the component's connectivity and interface requirements. The pinout is as follows:
Supports simultaneous data transmission (TX) and reception (RX).
Finding for higher-speed communication (up to 1 Mbit/s)
The RS232 standard is rated for up to 50 feet (15 meters) at 9600 baud, but this depends on cable quality and environmental noise.
If you want, I can: provide a printable one-page datasheet PDF, generate a PCB footprint and schematic symbol, create example firmware for an MCU (C for STM32 or Arduino), or adapt the specs to a specific sensor type (temperature, humidity, pressure, gas, particulate).
