+Overview
+********
+
+This shield supports mt9m114 camera modules which use a 24-pin FPC connector and a DVP
+(Digital Video Port), aka parallel interface. These camera modules are compatible and provided
+together with the i.MX RT1050, RT1060 and RT1064 EVKs as specified here `Camera iMXRT`_.

+Requirements
+************
+
+This shield can only be used with a board which provides a configuration for a 24-pins FPC
+connector with DVP (parallel) interface, such as the i.MX RT1050, RT1060, RT1064 EVKs.
+
