I like Arduino Nanos. They’re cheap. They work. They’re small. But they’re a bit fiddly, what with their breadboard legs and tiny pin labels. Wouldn’t it be nicer to use them as self-contained units, with Dupont wires coming from the pins?
This is where nspohrer’s Arduino Nano case with completely accessible pins comes in:

I’ve even included the original SVG so you can make custom versions. Please ignore the “micro” in the name … they are really for the Nano.
