When you got everything working but then realized it's a prototype case and there's no USB cutout yet.
Case was designed by my friend when I released my IIICC, been working on it since.

Hello everyone! I'm making a custom keyboard and need an advise.
I would use 2x I2C expander. This way you have 8x8 matrix on each expander and on top of that you can easily add more modules in the future. Just use more expanders. Here you have an example of 3 split keyboard based on I2C expanders.

Documentation on IO expanders?
For a working I2C expander based keyboards you can check my IIIC and Chordie. Sadly you can't get away from writing your own matrix scanning as there's no easy way to make reading I2C expander states in QMK. MCP23017 and MCP23018 have the same register addresses so there's no problem with moving the code between those two.

Custom matrix scanning help
You can check my code for IIICC. I am scanning 3 I2C expanders to combine the data into one scan result.

Some Help with the Preonic Rev 3 Encoder Implementation
Encoders change states following Gray code. There's a moment where A and B pins are all connected to C thus why you are having such issues. Check data sheet for the Output Table. To make it work you will have process those keys on your own and encode it the same way it's done with rotary encoders in QMK. It's easy actually. You can check my code here.

Any Existing Keyboards Built With Pro Micro and MCP23018?
My IIICC is one of them. For making it work you have to write your custom matrix scanning. Take a look at my src it's all there. Let me know if you have any questions.

Where I can buy mechanical keyboard switches? (physical store preferred)
Bro. I'm in Gent and I recently bought stuff to build 10x dumbpad RGB.

How to build a macropad guide (dumbpad)

Dumbpad v3 build including hotswap and rgb
Some of you may already know the dumbpad created by imchipwood ( https://github.com/imchipwood/dumbpad) which is a 4x4 Macropad with an encoder. I took the liberty to create a new version of the pad that adds hotswap Sockets and per key RGB to the original design.

Lily58 Pro vs Sofle v2, which one do you prefer?
i made dumbpad; It's 4x4 with encoder on the side . On /r/olkb and /r/MechanicalKeyboards, you can search for marco pad for 3x3, 3x4, and so on that supports encoder.

Hi, I've got a dumbpad macropad available - see this post for more info: https://www.reddit.com/r/mechmarket/comments/ltpd93/service_build_service_with_instock_parts_for/ I've also got a range of switches for trying, I haven't had time to update this list lately, but it might give you a rough idea: https://www.reddit.com/user/hectoring/comments/ivppks/switches_available_for_testing/

Keyboard Builders' Digest / Issue 15
A low budget build by u/cucumbermemes: impchipwood's dumbpad (git).
What are some alternatives?
When comparing IIICC and dumbpad you can also consider the following projects:
klepcbgen - Generates a KiCAD schematic and PCB layout using a Keyboard Layout Editor json file as input
Lotus-Keyboard - A split ergo linear keyboard derived from the Lily58 family
miryoku - Miryoku is an ergonomic, minimal, orthogonal, and universal keyboard layout.
ferris - A low profile split keyboard designed to satisfy one single use case elegantly
Chordie - A chording keyboard you shouldn't be scared of
nano-trackball - A very small trackball-only mouse. Mechanical files, PCBs, and firmware all included.
