Dimensions (mm)
Wi-Fi® 802.11 b/g/n
Network Controller Module
Model: SN820X
The SN820X is a family of small, low-power, self-contained, cer-
ti ed Wi-Fi® network controller modules that provide simple
serial-to-Wi-Fi® connectivity to the internet. These modules
are an ideal solution for device manufacturers who are looking
to add wireless connectivity to home appliances, smart energy
systems, healthcare and industrial control equipment.
The SN820X modules are enabled with Broadcom Corporation’s
Wireless Internet Connectivity for Embedded Devices (WICED)
architecture. They can host the Wi-Fi®, TCP/IP network stack, se-
curity supplicant, and other network application features. Those
features are supported by the Murata Simple Network Interface
Controller (SNIC) software and EZ Web Wizzard™ platform. The
modules are also compatible with Broadcom WICED SDK.
