sharkopad is a 6-key macropad with a rotary encoder & an oled screen. it will be your cutest & most favorite desktop buddy :)
features:
- 6 customisable keys
- backlights!!
- a rotary encoder
- a screen
- a yummy shark body
planned features:
- oled screen will show eyes and emotions
- rotary encoder changes layers so you can access more functions
- actually functioning backlights
these firmware changes are hard to test without the actual hardware so i will update it after i assemble it !!

Questions
How big is the Sharkopad PCB?
It measures 50.1 × 107.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sharkopad use?
21 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 Sharkopad KiCad files?
From the bucketfish/sharkopad repository on GitHub, at the commit this page was made from: the board is pcb/sharkopad.kicad_pcb and its schematic pcb/sharkopad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sharkopad design in my own project?
Its repository states no licence, so its author keeps all rights: ask bucketfish before reusing the design.
