+# SegfaultPad
+This is a random macropad I designed. It has controls for media, coding, and arrow keys, because
+I am currently using a 60 percent keyboard. The firmware is coded with KMK in Python because I was a
+little rushed, but I am planning on rewriting it in Rust from scratch soon. It is 4x4, and has no LEDs
+or stuff that could be distracting. I was inspired by some of the older, 80s design, and I probably
+had the most difficulties with the CAD modeling, as FreeCAD kept crashing and erroring.
+
+## CAD
+This is a screenshot of how it all fits together. I couldn't find good ways of positioning models, so
+it does not have the MCU or keyswitch + keycap models in it. All CAD models can be found in the `cad/`
+directory. The CAD models were originally designed with FreeCAD (not something I want to repeat) and tweaked with
+PrusaSlicer, but were remodeled in Fusion 360. I included the FreeCAD documents as well because the final result does contain some meshes, and so I wanted it to be more accessible.

+
+## PCB
+The PCB was designed entirely in KiCAD. Files can be found in the `pcb/` directory. I used the [OPL](https://github.com/seeed-studio/OPL_Kicad_library) KiCAD library, and the [ScottoKeebs KiCAD](https://github.com/joe-scotto/scottokeebs/tree/main/Extras/ScottoKicad) library. You can put both of these folders into the `libraries/` directory.

+This is my schematic:

+## BOM
+This is my Bill Of Materials, and should be everything necessary to build my macropad.
++ Cherry MX Blue Keyswitches (x16, greens if blue is not possible)
++ PCB (x1)
++ XIAO Seeed RP2040 (x1)
++ Through-hole diodes (x16)
++ Blank DSA Keycaps (x16)
++ Same bolts as the OrpheusPad (M3 I think?) and fitting nuts (4x of each)
