If you're looking for more information on the HW-044 or want to get started with your project, here are some additional resources: Data transmitted from the module to the external device

The is a hardware module based on the MAX3232 IC , designed to serve as a TTL to RS-232 converter . It allows microcontrollers (like Arduino or ESP32) to communicate with serial devices that use higher-voltage RS-232 signals.

💡 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.
