The MU series from Circuit Design are modems for embedding in industrial equipment. They incorporate the RF circuit required for radio communication and a CPU for control, and data is exchanged with an external CPU using the UART serial interface based on commands. The MU-2-R is a 434MHz low-power radio modem, supplied with an antenna. This complete solution allows you to develop equipment quickly using built-in radio, without having to pay much attention to the high frequency element. The MU-2-R also features FEC (Forward Error Correction) employing Reed-Solomon code. This ensures reliable radio communication even with a weak electric field or when burst noise is present.
