FGM230S Sub-GHz IoT Module and Development FGM230S Radio Board Kit
Silicon Labs' long-range sub-GHz IoT wireless connectivity is not susceptible to 2.4 GHz interference
Rapidly create security, lighting, smart home, metering, and building automation systems with Silicon Labs FGM230S module. This module provides sub-GHz IoT wireless connectivity with a long range that is not susceptible to 2.4 GHz interference. The single-die, multi-core solution provides excellent security, low power consumption with fast wakeup times, and integrated wireless connectivity for a power amplifier that enables the next generation of secure connectivity for IoT devices.
The FGM230-RB4328A high security FGM230S radio board and the FGM230-RB4328B medium security FGM230S radio board are designed to work with the WSTK main board (not included) to support the development of wireless IoT devices. Sub-GHz wireless protocols are used for Wi-SUN, connect, proprietary, sidewalk, and WM-BUS. The kit includes a +20 dBm 868 MHz or 915 MHz radio board that provides a complete reference design for the FGM230S module with the matching network for +14 dBm covering 868 MHz or 915 MHz. The FG23 pro kit provides the tools for developing high-volume, scalable sub-GHz wireless IoT applications.
