DIN Rail Mount for Arduino UNO/Mega

This is a neat solution for accommodating an ARDUINO MEGA 2560 Rev3 and cloned variants on DIN rail systems.It is simple enough to attach the Mega 2560 to the carrier mount, but not with the supplied bolts....which risk crunching PCB components....as their heads are too large to fit between some items on the board.They are not self-tapping screws, just ordinary threaded bolts which are hard to screw into the plastic holes, which in the long run would wear away the bore. Best not to even go there.The solution was to use six M2 10mm bolts, with washers and nuts, which makes a perfectly secure fit, sliding through without damage to the mounting....and more importantly, the heads safely clearing all PCB components.More disconcerting was the vertical wobble, even if the Mega 2560 is not fitted with a shield. The mount does not sit quite vertical. If the foot in contact with the rail was twice as wide on the facing (Mega) side, then this may have mitigated this discrepancy.Packing the mount's sides with other solidly fitting standard DIN components did not help much to stabilise the mount....it may require these to be directly superglued to the mounting plate, to meet stability requirements for installation in mobile devices.There are some well considered anchors on the mount, with some thoughtfully provided cable-ties for binding USB and Power input lines in situ.It is expensive for what it is, and somewhat lacking the usual locked-in precision of DIN accessories.
