+nRF7002 EB II
+#############
+
+Overview
+********
+
+The nRF7002 EB II is a versatile evaluation kit in the form of a thumbstick shield which connects to
+compatible Nordic host boards using the Nordic edge-connector.
+
+The nRF7002 EB II unlocks low-power Wi-Fi 6 capabilities for your host device. It supports dual-band Wi-Fi
+2.4GHz and 5GHz, and is based on the nRF7002 SoC. The shield also supports nRF7001 and nRF7000 SoCs
+through variant overlays.
+Seamlessly connect to Wi-Fi networks and leverage Wi-Fi-based locationing, enabling advanced
+features such as SSID sniffing of local Wi-Fi hubs.

+   nRF7002 EB II
+
+Requirements
+************
+
+The nRF7002 EB II board is designed to fit straight into a Nordic edge-connector and uses SPI as the
+communication interface. Any host board that supports the Nordic edge-connector can be used with
+the nRF7002 EB II.
+
+Prerequisites
+-------------
+
+The nRF70 driver requires firmware binary blobs for Wi-Fi operation. Run the command
+below to retrieve those files.
+
+.. code-block:: console
+
+   west update
+   west blobs fetch nrf_wifi
+
+Usage
+*****
+
+The shield can be used in any application by setting ``--shield nrf7002eb2`` when invoking ``west build``.
+
+Shield Variants
+***************
+
+The nRF7002 EB II has several variants to support different nRF70 SoCs and features:
+
+- ``nrf7002eb2``: The default variant using the nRF7002 SoC.
+- ``nrf7002eb2_nrf7001``: Variant using the nRF7001 SoC.
+- ``nrf7002eb2_nrf7000``: Variant using the nRF7000 SoC.
+- ``nrf7002eb2_coex``: Variant which includes the COEX pins. These pins are not routed to the
+  edge-connector on some boards, like earlier revisions of the Thingy53 than v1.0.0.
+
+SR Co-existence
+***************
+
+The nRF7002 EB II supports SR co-existence provided the host board supports it. The SR co-existence
+pins are connected to the host board's GPIO pins.
+
+Two Kconfig options are available to enable SR co-existence:
+
+- :kconfig:option:`CONFIG_NRF70_SR_COEX`: Enables SR co-existence.
+- :kconfig:option:`CONFIG_NRF70_SR_COEX_RF_SWITCH`: Control SR side RF switch.
+
