🐾 Kittypad
Kittypad is a custom 4-key macropad with a volume knob, an OLED screen, and a little RGB underglow, running on a Seeed Studio XIAO RP2040.
💡 Why I Built This
I wanted a quick media controller for my desk, but standard macropads felt a bit boring. I grew up loving Tamagotchis, so I thought it would be fun to put a tiny virtual pet on the screen that actually reacts when I type or turn the volume knob. Instead of just sitting there as a boring key block, it feels like a little desk buddy that hangs out while I work.
🛠️ The Hardware
Microcontroller: Seeed Studio XIAO RP2040 Keys: 4x mechanical switches (direct-pin to GND) Knob: EC11 rotary encoder (volume up/down, press to mute) Screen: 0.91" SSD1306 OLED (I2C) Lighting: 1x WS2812B NeoPixel for underglow

Questions
How big is the Macropad PCB?
It measures 105 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macropad use?
12 parts, built around the WS2812B. 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 Macropad KiCad files?
From the ItsStitchy/Kittypad repository on GitHub, at the commit this page was made from: the board is PCB/Macropad.kicad_pcb and its schematic PCB/Macropad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Macropad design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
