2. Brief Description

FC-703C RF transceiver module follows the wireless M-BUS protocol. It has a UART interface for serial communication and configuration. The dimension is 13.7*25.4*3.4mm.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.UART interface Wireless M-bus Module FC-703C is a good choice for water,gas and heat meter reading.
