Keypad PCB done! Top & Bottom preview

Now that I’ve finished, I’ve completed the PCB both images, the top and the bottom. I left the spaces for the M2 screws and already rotated everything, it was pretty easy!

Basically, I kind of left an array, a 7x7 matrix . The keys would be more or less standardized and the only difference would be in the pad — like, in the rubber, the material that you press to trigger that key. That kind of thing.

It turned out pretty nice. It’s simple, it’s actually simple to do this part, this kind of thing… That’s how it turned out.

I’m not sure if I’ll tweak it much to add things like a D-pad or other types of keys for navigation, functions, the numeric keypad itself , that kind of stuff.
