Our modules of the 4300 family have a built-in communication protocol and are optimized for long-range operation as well as low power consumption. They can be used for everything from simple cable replacement to complex applications.
The built-in protocol (RSL232) makes the modules easy to configure and prevents settings that violate regulatory standards. The 4300 family is designed for the license-free ISM/SRD bands of 433, 868 and 915 MHz, and the modules are delivered in several versions, depending on frequency and type of antenna; see the table below.
