Summary

This is an absolutely minimal plate for screwing a Raspberry Pi 3A+ to.

It is for when you want to fix one inside an enclosure with cable ties or a couple of bits of double-sided tape but not interested in decorative flourishes, lids etc.

The screw holes at the corners are only 2mm in diameter so quite a tight fit for the M2.5 screws used for the Pi. This is deliberate in case you want to use small self-tap screws instead. You can always ream the holes out a tiny bit to get an M2.5 started.
