UART interface Wireless M-bus Module FC-703C for smart metering application

 

 

 

Brief Description

 

FC-703C RF transceiver module follows the EN13757-4 protocol.The module adopts low-power and wireless SOC Si1000 Series MCU from silicon labs. It has a UART interface for serial communication and configuration. The dimension is 13.7x25.4x3.4mm.FC-703C can work in S, T, R2 and C mode. It works in sleeping mode with super-low consumption power and be wakened up via serial port. By mounting the module onto the user board,it is easy to use through serial port communication protocol.
