# Macropad
Hello! This is my first time designing a PCB and a CAD.
Designed using:
- KiCad - Made a ton of revisions
- OpenSCAD then FreeCAD (Fusion 360 doesn't work on my mac lol) Got like 400 constraints in my freecad project
- Python firmware
## Notes
Making the pad was fun ^.^ but I was just too paranoid that something would go wrong and made 15+ revisions lol. Ended up learning how to use OpenSCAD and FreeCAD.
## BOM
- 1 SEEEDUINO XIAO RP2040
- 16x [Kailh Choc V2 switches](https://www.kailh.net/products/kailh-choc-v2-low-profile-switch-set)
- 16x 1N4148 diodes
- 1x SSD1306 128x64O LED (5V VCC, 3.3V logic, I2C)
- 4x [SK6812-MINI-E LED](https://www.adafruit.com/product/4960)
- 2x 4.7k resistor
- 4x 0.1 uF capacitor (code 104, not obligatory but best have)
- 1x 1 uF capacitor (105 not obligatory)
- 4x same screws as orpheuspad and corresponding nuts
- 1kg of 99.99% gold please UwU

NOTE: I will need a 0.96” SSD1306 OLED screen that accepts 5V with 3.3V logic
The resistors are allso probably optional - but suggested by reddit
