Can someone help me out? I'm at work, ready to drill two PING mounting holes in aluminum, but I left my PING at home. Need the x & y distances for the two holes and diameter. Thanks!

BTW, it's to mount a PING on the front of this Flame-Boe-Yant robot:

    This appears metric friendly.

    The mounting holes (centers) are 40.0mm away in the X direction and 16.0mm in Y direction.

    The holes are 3.25mm in diameter (measuring as if there were four holes).     (Go with Ron's diagram.)

    4-40 machine screws fit through the holes. There's not a lot of clearance between the mounting holes and the transducers.

    Edit: Sorry erco, I don't know where that 20mm (as earlier posted) came from (other than my brain (I interrupted doing taxes to measure)).

    I doubt it comes as a surprise (nor should it) the actually PCB dimensions don't exactly match the diagram. Most dimension are off by 0.1mm. The long dimension is off by a couple of tenths. Not that this is a big deal.
