Overview
MacroCAD is an open-source printed circuit board by gismondisimone, from the gismondisimone/MacroCAD repository on GitHub, published under the MIT licence. It is a 2-layer board of 72 × 95.5 mm with 28 parts on 26 nets, routed with 154 tracks and 4 vias.
Its parts include 12 diodes, 12 switches, 1 IC and 1 connector. It belongs with the keyboards and input boards of this library.

What is This?
It's a custom macropad built with the Seeed Studio XIAO RP2040, QMK firmware. It's designed by a CAD user for CAD users. The design is as cool as fragile.
Features:
- 3x4 Matrix - Just numbers and a dot key and enter key.
- OLED Display - It's a cool add-on though I will update its functions in the future.
- QMK Firmware - Open-source, because we like freedom.
How It Works:
This macropad runs QMK, which means you get:
- Custom Keymaps - Map macros, media keys, or even full-blown scripts.
- Dynamic Layers - More functions per button? Yes, please.
- Display Support - A cat that reminds you to work on your project? An integration with Hackatime that shows up your hours spent on designing.
Default Keymap:
(Change it if you want, you could delete the enter key and put a shortcut for your CAD software).
3x4 Button Layout:
| Row | Key 1 | key 2 | Key 3 |
|---|---|---|---|
| 1 | 7 | 8 | 9 |
| 2 | 4 | 5 | 6 |
| 3 | 1 | 2 | 3 |
| 4 | 0 | . | ent |
How to Build It:
Step 1 - Put the inserts in the holes on the bottom part.
Step 2 - Align holes on the PCB to the holes on the bottom part.
Step 3 - Align holes on the top part to the holes on the PCB.
Step 4 - Put two M4x25 screws in the holes.
Why?
I built this macropad for Hackpad-an awesome Hack Club YSWS project. With the (hopeful) funding provided by the project, I wanted to create something that's as practical as it is professional. Whether you're designing your favorite projects, this macropad is my way of saying:
why settle for ordinary when you can hack something extraordinary?
The Biggest Challenge:
It's my second time designing a PCB, I'm slowly improving.
Future Plans (Maybe):
- Encoder?
- Bluetooth support? (Would need a battery)
- Improving the design with aluminum frame, LEDS?

Questions
How big is the MacroCAD PCB?
It measures 72 × 95.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MacroCAD use?
28 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the MacroCAD KiCad files?
From the gismondisimone/MacroCAD repository on GitHub, at the commit this page was made from: the board is PCB/MacroCAD.kicad_pcb and its schematic PCB/MacroCAD.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MacroCAD design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
