Radiocrafts AS has launched a compact Wireless M-Bus RF module for use in automatic metre reading (AMR) and smart metre applications. The company claims the RC1180-MBUS is the industry's first compact all-embedded module compliant with the Wireless M-Bus standard, supporting two-way communication in S and T modes. It meets the Wireless M-Bus specification for all S1/2, T1/2 and R2 modes, and operates at 12 channels in the 868-MHz frequency band.

The surface-mount RC1180-MBUS RF transceiver module measures 12.7 x 25.4 x 3.3 mm including shielding, replacing tens of components compared to a discrete design, said Radiocrafts. The module offers a UART interface for serial communication and configuration, and a one-pin antenna connection. The new module supports two-way communication, enabling not only metre reading but also valve control and data acknowledgement.

The module is pre-certified for operation under the European radio regulations for licence-free use. When used with quarter-wave antennas, a line-of-sight range of 500-600 metres can be achieved. The module is designed for use in battery-operated systems with up to 20 years of battery lifetime.

Module and demo kits are available now. The product is priced at less than Rs.430.00 ($10) in volume.
