[Introduction]：The E51 series IoT wireless module is a Wi-Sun module that provides long-distance, low-power transmission. It uses the EFR32FG25 series chip and supports the orthogonal frequency division multiplexing (OFDM) modulation technology introduced in the Wi-SUN field area network (FAN). It has a small form factor, rich interface resources, and support for user secondary development, making it widely applicable in the IoT industry.
