New Concept Digital Keypad 6 - LED Cross Contamination

New Concept Digital Keypad 6 - LED Cross Contamination
6th in the series, I want to scrap the old concepts of digital keypads, used in access control.
Design a keypad that can be milled out like a clam shell, rounded enclosure, with minimum of buttons, that are illuminated, say with neopixels, so any color, so it begins.
