In my last post, I mentioned the Pimoroni Tiny 2040. While it probably won’t die by just dangling off it the end of a USB cable, or tossing the naked device it in your bag/pocket, I prefer to have a small case around it to have some protection and make handling easier.
This also has the benefit of looking more professional when using it at work, compared to the “uh, are you sure this is a good idea” look I get when plugging PCBs directly into USB ports.
The design itself is pretty basic:
- as small as possible
- a top and bottom half that snap together securely when assembled
- a slight recession on the bottom to accommodate the parts on the underside of the PCB
- holes for the two buttons
- a thin layer above the LED so it is protected, but still can be seen/used
One reason I like using this case, is that I can print a few in different colors and switch them out based on the payload (e.g. red for dangerous, green/blue/yellow for safe, testing, informational).
I uploaded the design to Thingiverse for everyone to access: https://www.thingiverse.com/thing:5994359
