Core Positioning: Based on the EFR32FG25 chip, this is EBYTE’s first module supporting the Wi-SUN (Wireless Smart Utility Network) protocol. Wi-SUN is an open standard protocol designed for smart cities and smart utilities, offering high capacity, high reliability, and long range.

Key Features:

• Powerful Processing: ARM Cortex-M33 core running at 97.5 MHz, with 1152 KB Flash and 256 KB RAM — ample computing headroom.
• OFDM Modulation: Supports Orthogonal Frequency Division Multiplexing (OFDM), achieving data bandwidth up to 3.6 Mbps — far exceeding traditional FSK modulation.
• Long-Range Communication: Operates in the Sub-1GHz band (470–510 MHz), delivering 0.3–2.5 km wireless coverage in dense urban environments.
• Rich Interfaces: USB 2.0, EUART, SPI, EUSART, PWM, ADC — convenient for secondary development.

Suitable Applications: Smart street lighting and environmental monitoring sensors in smart cities; electricity meter concentrators in smart grids; repeaters or edge gateways in industrial IoT.
