Wireless transmission module based on the 433MHz frequency band development. Converts RS485 received data signals into wireless signals and can communicate wirelessly with another wireless transmission module within a certain distance. The receiving end captures the wireless signal and converts it back into an RS485 signal for output. Users can deploy multiple wireless transmission modules for data transmission, eliminating the need for extensive signal cabling. Modules are operational once powered and connected to RS485 devices, enabling convenient remote data exchange and avoiding transmission issues caused by corroded, damaged, or poorly connected cables. The module requires configuration of only two parameters—baud rate and channel—settable via DIP switches, simplifying setup and improving user experience.
