SRV-1 Blackfin Controller and Camera Module

SRV-1 Blackfin Camera with 500MHz Analog Devices Blackfin BF537 processor, 32MB SDRAM, 4MB Flash, and Omnivision OV9655 1.3 megapixel camera, 2.5mm f2.0 lens (90-deg field-of-view).

Price does not include WiFi expansion board. See wide-angle lens and 90-degree camera mount option.

Note that the SRV-1 Blackfin Camera, when shipped without a Matchport WiFi module, configures UART0 in firmware for 115kbps.
