OEM LCVR Board Dimensions
Mounting and connecting to your liquid crystal variable retarders (LCVR) controller board

The LCVR Driver Wildcard (specifications here) is a small 2"x2.5" printed circuit board (PCB). While it is intended for use with Mosaic's single board computers (specifically with the PDQ Board and the Analog I/O Wildcard), you can also use it as a stand-alone driver board for any nematic liquid crystal device, such as the LC retarders and phase modulators available from Thorlabs, Meadowlark, or Edmund Optics. In that case, you may need details of its geometry, connector placement, and mounting holes.

The following figure shows the precise dimensions of the board.
