💡 Some HW-044 converters are reported to have incorrect internal wiring, occasionally appearing as DTE (Data Terminal Equipment) when they should be DCE (Data Circuit-terminating Equipment). If your device fails to communicate, you may need to swap the TX/RX lines or check the board's specific trace layout.
Programming microcontrollers that require a serial bootloader. hw-044 datasheet
It is built around the MAX3232 IC , which is an upgraded version of the classic MAX232 that supports a wider voltage range (3.0V to 5.5V), making it compatible with both 3.3V and 5V logic systems. Core Specifications 💡 Some HW-044 converters are reported to have
RS-232 bus-terminal ESD protection up to ±15 kV (Human-Body Model). Channels: 2 Drivers and 2 Receivers. Pinout and Connections It is built around the MAX3232 IC ,
HW-044 5V Relay Module Primary Function: Electromechanical Relay Switching Module for Microcontrollers (Arduino, ESP32, PIC, STM32, etc.)
