Ebyte E50-900NW20SX UART EFR32FG23 868/915 MHz 20dBm Wireless SOC Module

Ebyte E50-900NW20SX UART EFR32FG23 868/915 MHz 20dBm Wireless SOC Module

The E50-900NW20SX wireless module is an ideal solution for sub-1 GHz IoT wireless connectivity for smart home, security, lighting, building automation and metering. It is equipped with Silicon Labs' EFR32FG23 series chips, which can achieve wireless broadcasting up to 0.3~2.5 kilometers with minimal data loss in dense urban and canyon environments. At the same time, the module also carries firmware that supports WM-BUS (Wireless M-BUS) bus technology.

The E50-900NW20SX wireless module firmware is developed based on the EN13757-4/3 European standard, which can realize intelligent general instruments, data concentrators, and mobile computers. Seamless SUB-GHz RF communication protocol between meter devices and heat distribution meters.

The E50-900NW20SX wireless communication module can be used as an SoC (system on chip) development platform. It has the characteristics of small size, rich interface resources, and supports user secondary development, and can be widely used in the Internet of Things industry.
