Ultra-low-power sub-GHz RF networking

The RM-SS2 is a sub-GHz radio module targeted for applications where proven reliability, highly flexible network and low-power performance are key requirements.

The RM-SS2 module is based on STM S2-LP transceiver and ultra-low-power STM32L0 host MCU. The module is principally designed for the ISM (Industrial, Scientific and Medical) and SRD (Short Radio Device) frequency bands, ranging from 868 to 930 MHz. Module features top-notch RF performances and unparalleled energy efficiency extending battery life from months to more than 10 years.

RM-SS2 module is ready for SIGFOX, Wireless M-Bus, and IEEE 802.15.4g networking connectivity, simplifying the design of IoT applications.
