SnakeEyes enables cost-effective FRC vision targeting and lets you customize your vision application. You pick your ideal stack of Raspberry Pi version, camera, LED color, and even software application! Power to your Pi is provided via passive PoE, which powers an efficient, onboard 5V buck regulator, and 4x dimmable, high power LEDs brighten any arena. A Raspberry Pi Cam V2 mounting pattern lets you select between a standard or NOIR camera (see our SnakeEyes: Green for use with standard camera). Take control of your vision program with SnakeEyes!

Note: Far Red LEDs are far less distracting to field operators than equivalent green LEDs due to human vision sensitivity, but are just as visible to cameras.
