Here is a simple sketch to test your HW-044.

The HW-044 uses a 3-wire SPI-like interface:

The is a compact RS232-to-TTL serial port converter module built around the MAX3232 integrated circuit . This module is an essential tool for projects that require communication between a computer (RS232 levels) and a microcontroller (TTL levels), such as an Arduino or ESP32. Technical Specifications

: Measuring roughly 31mm x 32mm, it fits easily into project enclosures for industrial equipment upgrades or radio modifications. Common Use Cases

supply rail, the core MAX3232 IC on the HW-044 features an upgraded internal capacitive charge pump. This architectural improvement lets the board operate directly from logic levels. MAX3232 RS232 to TTL Serial Port Converter Module

The "HW-044" code is also used for products unrelated to electronics, such as LED desk lamps, decorative furniture nails, and even government procurement contract numbers. This article focuses on the most common electronic modules, as they are the ones for which a "datasheet" is most relevant.

Connects to the Negative (-) power terminal of your target circuit or load.
