+description: |-
+ The Omnivision OV02A10 is a low-cost, high performance, 1/5-inch, 2 megapixel
+ image sensor, which is the latest production derived from Omnivision's CMOS
+ image sensor technology. Ihis chip supports high frame rate speeds up to 30fps
+ @ 1600x1200 (UXGA) resolution transferred over a 1-lane MIPI interface. The
+ sensor output is available via CSI-2 serial data output.
