Releasing this out in the wild as an incomplete design I was working on as I have changed some of my design descision so won't be completing this one.
It is for a standard computer numpad, uses Cherry MX style switches with single colour, per key LED backlighting. The backlighting is controlled through a LED Matrix. Keys are spaced at 19.05mm spacings with the Plus, zero and Enter being 2U keys with the rest being standard 1U keys. Most of the key matrix and LED matrix routing is done but need to finish the MCU & LED matrix driver components and routing.
Just to reiterate, this is not a completed design.
