Embedded low power radio modem

Supplier: Circuit Design

The Embedded industrial radio modem MU-1-R is a radio modem for transmission of serial data. Using a simple system of commands, the user can concentrate on designing the transmitting and receiving protocols for the data using the commands, without needing to be aware of the radio component control. By using a UART interface for transmitting and receiving data and for issuing commands, it is possible for the user to develop systems quickly.
