Summary

Very simple bracket for this Raspberry-Pi compatible M12 camera board http://www.ebay.com/itm/321424952350 which has 4x mounting holes for M2 screws with nice exposed copper areas on the PCB around the holes. Which are different electrical nets! So if you screw it into an aluminum plate, it shorts the power supply. So you need a plastic bracket, and here it is. The photo shows how I'm using it (I replaced the M12 lens with a SUNEX one, but it's the same board). Mounted as shown, the camera is in portrait, rather than landscape mode.
