Overview
VPad is an open-source printed circuit board by arivvid27, from the arivvid27/vPad repository on GitHub. It is a 2-layer board of 95.3 × 67.3 mm with 8 parts on 16 nets, routed with 80 tracks and 3 vias.
It is built around the SK6812MINI-E. Its parts include 5 switches, 2 diodes and 1 IC. It belongs with the RP2040 boards of this library.

Current Features:
- Mechanical Switches (MX Basic | Macros)
- Two NeoPixels (Ambience)
- Encoder + Switch (Volume/Brightness Control/Mute/Unmute/More Macros)
What's Holding it Together;
- Not Duct-Tape this time
- KMK Firmware
- Circuit Python
WIP Stuff:
- Custom Software to work with this pad
- Mini OLED Screen
- Better Ambient Lighting (Underglow, Keycaps)
Future Stuff:
- Expand to full Keyboards
- Mice?
- Definitely a Better case 😭
- More Switches (Imma find those push things where they stay on until you push them again)
Challenges:
I was quite a bit stumped on how to use KiCad. The tutorial helped a ton. I also have never imported anything into F360... so it took me a while to figure that out. Overall, I think I learned a lot from this, and I will continue to make PCBs now that I know how to. :)

Questions
How big is the VPad PCB?
It measures 95.3 × 67.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the VPad use?
8 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 VPad KiCad files?
From the arivvid27/vPad repository on GitHub, at the commit this page was made from: the board is PCB/vPad.kicad_pcb and its schematic PCB/vPad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the VPad design in my own project?
Its repository states no licence, so its author keeps all rights: ask arivvid27 before reusing the design.
