+WUXI_OV5640 Camera Module
+#########################
+
+Overview
+********
+
+This camera module connector comes from Wuxi A-KERR Science & Technology containing
+an OV5640 image sensor which provides the full functionality of a single chip 5
+megapixel (2592x1944) camera using OmniBSI™ technology in a small footprint package.
+
+More information about the OV5640 can be found at `OV5640 camera module`_.
+
+This module uses a 42-pin connector with MIPI CSI-2 interface which is available on
+NXP i.MX RT11XX series.

+Requirements
+************
+
+This shield can only be used with a board which provides a configuration
+for a 42-pin connector with MIPI CSI interface, such as i.MX RT1170-EVK.
+
+Programming
+***********
+
+Set ``-DSHIELD=wuxi_ov5640`` when you invoke ``west build``. For example:
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/subsys/video/capture
+   :board: mimxrt1170_evk/mimxrt1176/cm7
+   :shield: wuxi_ov5640
+   :goals: build
