Keeblet

I just got a set of 13 different Kailh Choc switches, to see which ones are best for a given use case, and I needed to mount them to something — the Keeblet is just the perfect vehicle for this! Since the two red switches -- Kailh Pro and Transparent Red  — are practically identical from the point of view of feel, I only needed to make 2 new Keeblets, for a total of 12 switches:

The transparent key caps are perfect for this, because you can see which switch is which without having to remove them!

As usual, everything starts with the PCB design.

Nothing fancy. The minimal SAMD21 schematic with USB, plus six keys with diodes, a LED and a programming header. As usual in my projects the header has staggered pins to allow plugging in a male header without soldering.

The board will use choc switches, because I really like them. In hindsight, I should have designed some kind of a frankenfootprint so that any switch could be used — maybe I will do that in the next version.
