Hi,
3mm screws seem to be a bit too big for the mounting holes in the thunderborg. Should one use 2mm?
Also: is there a technical drawing of the thunderborg boards available?

Thanks!

The holes are intended for M2.5 screws to match the ones on the Raspberry Pi. They are located in the same places as the Pi Zero holes.

I have attached a scale drawing with the major dimensions below (all units are mm).

I tried my best to make a drawing with CorelDraw which, printed, was helpful for me as a template when drilling. attached is a zip containing the .cdr, .eps and .svg
For my purpose it is accurate enough.
