This document is being revised over time. When creating new board designs, check the recommended specifications below before beginning. Both mounting hole size and spacing are standardized and must be followed for WARG hardware.

Common Mounting Holes Sizes

Going forward, all general custom EE flight PCBAs will follow the following mechanical mounting hole and pattern specification listed below. These mounting holes can be found in our Altium library.

...

• M3

  • 3.40 mm hole diameter

  • 0.10 mm hole diameter tolerance

  • 6.00 mm annular ring diameter

  • Advised on any PCBA exceeding a board area of 900 mm^2 (this is being most boards)

• M2.5

  • Not recommended

• M2

  • 2.40 mm hole diameter

  • 0.10 mm hole diameter tolerance

  • 4.20 mm annular ring diameter

• No Mounting Holes

  • Do this for any smaller boards because running holes smaller than M2 is not really practical as per past conversation .

  • Used on any PCBA with area less than 750mm^2

  • Mounting will be done with double sided sticky tape or Velcro and the board should be designed to facilitate this.
