Copper Standoff M2.5×11 Spacer

This is a copper standoff M2.5 x 11mm. It can be used to make 11 mm clearance between your Raspberry Pi and the HAT, and is perfectly fitted with the stacking GPIO header.

It is the copper standoff used by Witty Pi 2, Witty Pi 3 and Witty Pi 4, and you can also use it on Witty Pi 4 Mini or your own HAT for Raspberry Pi, if you are going to use the same stacking GPIO header.

You will need 4 pieces of such copper standoff for one board. This copper standoff can be used with this copper screw together (one standoff with 2 screws).
