Main components

README.mdRustambek's first-ever hackpad
I wanted to make hackpad with built-in OS. You control OLED display with keycaps or switch the mode to control PC. Sadly, I ended up with simple project that can only interact with PC not with OLED display. However, I haven't given up hope. When I recieve parts, I will make some modifications in code in order to try reaching my goal
Overall design
What's special?
- You can play games conveniently (e.g. snake game) that can be controlled with arrow keys
- RGB led will blink when you tap a key
- OLED Display shows instructions on how to use the hackpad
Features
- RGB LED will blink green if Up, Down, Right, Left arrow keys or Enter key are pressed
- RGB LED will blink red if Enter or Backspace key are pressed

Questions
How big is the HackpadOS PCB?
It measures 62.4 × 77.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the HackpadOS use?
11 parts, built around the SK6812. 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 HackpadOS KiCad files?
From the odyesey/hackpad-hackclub repository on GitHub, at the commit this page was made from: the board is PCB/HackpadOS.kicad_pcb and its schematic PCB/HackpadOS.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HackpadOS design in my own project?
Its repository states no licence, so its author keeps all rights: ask odyesey before reusing the design.
