Würth Elektronik Radio Modules are compact and cost-effective radio data transmission modules for wireless half-duplex communication. The radio modules come with an integrated microprocessor that controls data communication, handles packet and checksum generation, monitors channel access, and re-transmits lost packets. This enables the host system to not perform any radio-specific tasks. The radio modules can be configured in many ways and support data transfer with fast channel and address switching. These modules are application-specific for industrial applications.
