Camera Link

This PCB connects a Chameleon3 USB3 camera to pyControl. It takes "frame grab" and "sync pulse" signals generated by pyControl and coming out of a D-Series Breakout Board and routes them into the GPIO pins of the camera.

Additionally, the PCB has 3 controllable high power IR LEDs that provide light for the camera to see in the dark.
