ADXL345 - Triple-Axis Accelerometer mechanical layout

Dear Sir, in order to fix the module on a my pcb I kindly ask you the detailed mechanical keepout of your board.
External sizing and fixing holes also please quote from the two fixing holes and the connectors pads.
Looking forward to your reply.
Thanks in advance!
Grinch

The complete CAD files for this board are located here in Github: https://github.com/adafruit/Adafruit_ADXL345_PCB

Hi,
The Eagle cad at Github shows 0.8" pitch of the two Ø0.1" holes. I've scaled from the photo at https://www.adafruit.com/products/1231 and the pitch looks like 0.746". It is clear by looking carefully at the photo using the nine 0.1" pitch holes. (9-1)*0.1"=0.8" so the two larger holes can't be at 0.8" pitch as per the cad (the distance across the outer of the nine holes is greater on the photo than the distance across the two large holes).
Please advise the nominal design pitch of the two mounting holes. Please also consider including the board size and mounting hole pitch within the description/technical details for all Adafruit boards.
Kind regards, Tim

These are the files we use to manufacture the boards. I will check to see if there have been any recent updates.
