So I decided what components to use, I decided the following:
1x EC11 w/Switch
3x4 MX Layout
1x 0.91” i2c OLED
Seeed Studio XIAO RP2040
12x SK6812 RGB LEDs

Since there are only 11 GPIO Pins broken out, I’m going to solder the NeoPixel LED DIN Pin to the on-board RGB LED DIN Pin or via, this will allow me to also have RGB without having to compromise on my components selection. I could’ve tried using an I/O Expander IC like the MCP23017 or similar but that would’ve added cost and complexity, and since this will be the first time I make a macropad/keeb that will (or should) actually work, I wanna keep the hardware and firmware as easy as possible to reduce the chances of me fucking it up.

After deciding everything, I created a KiCad proj, downloaded the libs and added them to KiCad, opened lapse, and locked in and designed the schematic. Some pauses where my mouse was moving but nothing going on in KiCad was me searching up on google to fact-check my decisions, like how to wire the matrix and stuff. Sometimes I was going to the Hackpad docs (like for the OLED part), and sometimes it was when I was adding footprints or net labels, so sorry for those pauses lol.

Now all I have to do is add the RGB, double check everything, assign footprints, etc. Then I can move on to the PCB and CAD.
