CMOS Sensor

Using low cost and low power CMOS sensor from Omnivision OV7740 Supporting up to VGA, 60 fps CMOS sensor configuration through standard I²C interface

PSRAM as External Memory for Data Storage

Lower cost structure Also lower power vs. SDRAM/SRAM

SAM3S PIOs Parallel Capture Mode

No CPU involvement CPU in sleep mode during data transfer DMA from IOs to external memory
