CanoKey Nano-A PCB thickness and housing size

[Lillythefox]

Hello,

Im just wondering what PCB thickness you used for the Nano-A? Also dose it need a metal housing like the Nitrokey 3A Mini?

See how the PCB is in the metal housing so the components are not damaged.

The thickness of the PCB with housing should be 2.5mm. We don't have the housing design yet. A piece of paper sticked on PCB can be used for prototyping.
