Simple dual-panel design for sensor node. Can support an Up Board, a Rasp Pi, an Arduino, an Edison, or a Galileo board as processor, has a grid for Grove sensors, slots for wire management, and holes for a camera and a 4D display panel. Also has feet that can be adjusted to tilt the camera at a fixed angle, and slots to allow multiple sensor nodes to be stacked.
This is a 2D design but is implemented using OpenSCAD to allow parameterization.
