M5Stack Mechanical Key Button Unit

This is a simple 1-button unit from M5Stack. For those familiar with mechanical keyboards, the key is an MX-Style Blue Clicky Switch. This means the button provides tactile feedback when pressed, and at the same time you hear a "click" sound, which gives additional acoustic feedback. The keycap, the plastic button on the actual switch, is a DSA profile made of ABS. You can exchange this with other caps if, for example, you want a different color or profile. The unit has two digital IOs for querying the key status and for controlling the SK6812 LED.
