Overview
CommandPad is an open-source printed circuit board by SyedIhteshamuddin, from the SyedIhteshamuddin/CommandPad repository on GitHub. It is a 2-layer board of 87.5 × 73 mm with 22 parts on 24 nets, routed with 257 tracks and 24 vias.
It is built around the SK6812MINI-E. Its parts include 10 diodes, 6 switches, 1 IC and 1 connector. It belongs with the keyboards and input and lEDs and displays boards of this library.

Overview
This is my first complete hardware project, I have spent over 20+ hours on this project.

SCHEMATIC
I have used global tags in my schematic to make it clean and clear, But Assigning footprints and finding relevant 3d models for the components for me was a very difficult task :)
PCB LAYOUT
I have manually routed the PCB , it was somewhat challenging to overcome the Board Clearance issues. The PCB has 0 errors (DRC) except silkscreen warnings.
CAD Designing
I was CAD designing FIRST TIME. So, it was not easy for me. I have designed this case in Autodesk Fusion. This design is a "SANDWITCH STYLE MACROPAD" where it consists of two plates; Top plate, Bottom Case and PCB gets sandwiched between them. They are all screwed up with M3 Screws. All the design was done in +0.04 tolerance for better results!

| XIAO RP2040 | CircuitPython + USB HID | Processes inputs and sends keyboard/media commands |
status: The displayed volume percentage is an estimate, not the computer's actual volume reading.
AI Usage
I used AI to gather resources for footprints and 3d models, and also for Firmware. Rest all work is done by me! [ For Proof : You can check Lapse recording ]

Questions
How big is the CommandPad PCB?
It measures 87.5 × 73 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CommandPad use?
22 parts, built around the SK6812MINI-E. 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 CommandPad KiCad files?
From the SyedIhteshamuddin/CommandPad repository on GitHub, at the commit this page was made from: the board is PCB/CommandPad.kicad_pcb and its schematic PCB/CommandPad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CommandPad design in my own project?
Its repository states no licence, so its author keeps all rights: ask SyedIhteshamuddin before reusing the design.
