I've designed a number pad matrix this weekend. I'm calling it the Neobiscuit.

It's designed for hot-swappable Kailh Choc keys, and has support for addressable LEDs.
This is the first board design on the road to making my own keyboard. This one breaks out the rows and columns to a header so I can port ZMK to the microcontroller I want to use. Future versions may have the MCU onboard, or as a daughter board. I haven't decided yet. I'll switch to SMD diodes too at some point too. I went THT this time because I have a LOT of them, but It did mean I had diodes right where I wanted to route my traces. I'll also have to figure out the footprint for Kailh Choc stabilisers at as well.
