USB Keyboard Controller for Raspberry Pi input

[matisok]

I am building a button panel for my home with 20 buttons or so.

Each button will trigger an action through node-red on a Raspberry Pi.

Rather than using the GPIO pins, I would rather use a USB keyboard controller. Easier than wiring up GPIO's and also has more inputs.

But taking a USB keyboard apart and soldering wires onto the pcb of the keyboard is really tedious work.

So I am trying to find a USB Keyboard PCB control board with easier custom wiring somehow.

Anyone here in Maker land have any suggestions to this?

Try a USB number pad.

Why not try to re-solder it? It's tedious, but it sounds worth it to me.
