Hunter Douglas Duette Honeycomb button/IR board. 
Came from Duette motorized blinds. This is the board that contains the infrared (IR) sensor as well as the button you can press so that the blinds will go up or down.

Board reads: IRRF EYE REV. 2007
401rxr-005a02e_revB

In great working condition, these come from a non-smoking and pet-free home.
