NXP BTB-44 OV5640 Camera Module
###############################

Overview
********

This shield supports ov5640 camera modules which use a 44-pin board-to-board connector and
a MIPI CSI or DVP (parallel) interface. These camera modules are made specifically for and
provided together with NXP's i.MX RT1160 and RT1170 EVK boards.

More information about this OV5640 camera module can be found at `Camera iMXRT`_.

Requirements
************

This shield can only be used with a board which provides a 44-pin board-to-board
connector with MIPI CSI or DVP (parallel) interface where the pinouts are defined
as above, such as i.MX RT1160 and RT1170 EVK boards.

Programming
***********

Set ``--shield nxp_btb44_ov5640`` when you invoke ``west build``. For example:

.. zephyr-app-commands::
   :zephyr-app: samples/subsys/video/capture
   :board: mimxrt1170_evk/mimxrt1176/cm7
   :shield: nxp_btb44_ov5640
   :goals: build
