   14   The Omnivision OV02A10 is a low-cost, high performance, 1/5-inch, 2 megapixel
   15   image sensor, which is the latest production derived from Omnivision's CMOS
   16   image sensor technology. Ihis chip supports high frame rate speeds up to 30fps
   17   @ 1600x1200 (UXGA) resolution transferred over a 1-lane MIPI interface. The
   18   sensor output is available via CSI-2 serial data output.
