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.

Moonlander + Ploopy Nano : anyone else out there?
I have been using a Moonlander for a bit more than 2 years now and have been loving it! Up until a few months ago I used a Logitech M570 alongside it. Looking for a trackball at the office, too, I then went out and bought a Logitech M575 only to realize very quickly that it just is not the same. So my search for an alternative set in almost immediately. Luckily I was also following r/Trackballs and learned about the Ploopy Nano Trackball which I hoped would pair very nicely with my Moonlander. And indeed, it does! I am still getting used to the layout changes I had to make to accomodate the one missing thumb cluster but so far I am absolutely loving it!

My first Dactyl
It’s a Ploopy Nano. Been using it, with any mouse buttons mapped to left keyboard half for about 6 months now and it’s really helped keep my hands pain free.

Microsoft Ballpoint Mouse
The Ballpoints predate my time in the Hardware group by a few years, but I'd be surprised if anyone that worked on those devices would have expected the color to be so nice on the device all these years later, and that the plastic wasn't too brittle to keep it in use today. Might just be easier to take something like the Ploopy Nano and make a case for it to meet your needs vs. trying to retro fit the Ballpoint.

Experience customizing Raise Firmware
So far I've done 2 modifications in the form of Kaleidoscope plugins, both of which I've put up on Github for those curious: • Mouse Layer - This switches my homerow keys to mouse keys whenever mouse movement is detected: wallisc/Kaleidoscope-MouseLayer (github.com). I use to do this with Bazecor by creating a separate layer and manually switching to the layer using a layer shift, but found I used the layer so much that layer shifting became fatiguing for my finger. Then I heard of a modification in the ErgoMechKeyboards reddit where QMK was modified to trigger mouse keys on mouse which inspired me to try something similar. I'm a trackball user and I love this modification, it allows me to use the Ploopy Nano (https://ploopy.co/nano-trackball/) which has no mouse keys but I also enjoy it with my CST L-trac, which does have mouse keys but are stiff and generally less pleasant than the keyboard switches. For fun, I animate the color of all the keys I'm overriding with a rainbow shift effect, this is how it looks in action: https://imgur.com/a/ptOHkcS • Alt Tabber - This overrides certain keys when the left-alt is held. Primarily used for quick alt-tabbing: wallisc/Kaleidoscope-AltTabber (github.com). I have alt as a thumb key and using this I can change the F/J keys to turn into Tab so I can alt tab without moving my hand off the homerow. I also override 4->F4 because alt-f4 is handy. Currently I just set any overridden keys to red, but probably will update it to have some fun LED animations as well at some point Disclaimer: There's probably some inefficient code but at the very least it's fairly simple if people are just curious what a plugin code looks like.
- Possible to purchase *just* the nano board?
