Hello everyone. I'm not very technical, just beginning with raspberry pi etc
I'm trying to make some PDA-like devices from raspberry pi-s 3b and zero w. I configured them to connect to each other like in mesh network. For now everything works fine, they all are syncing without access to internet etc. I've got almost everything I need, but...
I can't find suitable keyboard for them! I can't sleep...
I need it to be:
-WIRED, not wireless! USB/micro usb/ GPIO ??
-small, so freaking small. I need two versions: 1st like in old phones (about 12 keys - you press "2" twice to get "B", once to get "A" etc); 2nd raspberry sized ~80 keys keyboard with tiny tiny keys
-not be as thick as raspberry pi
-have arrow keys, ctrl, shift, tab (the second one)
-additionally, I'd love it would have trackpoint (yes, this oldschool red nipple mouse dot from your grandma's laptop. I heard somewhere it's called "cat" but I'm not sure it's true), because trackpad is just too big...
Here are some examples:

Just that, but everything I found are some big keyboards for rpi/ remote sized wireless "keyboards" which works like sh*t etc... argh
I wonder, how about making keyboard by myself? If it's possible and not too hard to use few of for example waveshare 4x4 keypads? https://www.waveshare.com/4x4-keypad.htm
I found you can use them with arduino... How about raspberry pi? Could I connect few of them to one rpi? Maybe are there ones with bigger number of keys & designed for rpi?
I also found 5x2 keypad withg joystick (about like trackpoint!) https://www.waveshare.com/5-io-keypad.htm
What do you think? Do you know some keyboard whick would suit? Did you try making your own - is it a good idea?
