Visuals because everyone loves eye candy.

It's a custom keyboard built for infinite expansion through its module ports! It uses an Orpheus Pico, QMK firmware, and even more LEDs. The expansion modules could be literally anything! From a screen, a rechargeable battery, a buzzer, or even more LEDs!

• Keycool84 Layout – Possibly the best?
• Rotary Encoder – Twist for volume, scroll, or secret hacker functions.
• Clickable Encoder Button – Because sometimes, twisting isn’t enough.
• 61 SK6812 Mini LEDs – ✨Almost blinding✨
• Literally Infinite Expandability – Custom designed module slots that support chaining submodules together!

The infinitely expandable modules were built using an I2C bus! Also since the Orph Pico knows which modules are plugged in, certain modules could unlock further functionality from another! Like a button module being able to activate a haptic feedback (vibration) module. (This isnt built in yet // Software still WIP)

Each module slot has a 5V, EN, GND, SDA, and SCL lines. After a module is plugged in and ready to work it will pull its EN line high to 3.3V, letting the Pico know there is something there in that expansion slot!

I built this keyboard for Highway—an awesome Hack Club YSWS project mainly run by Alex Ren. (I helped run this event as one of the project reviewers!) I wanted to create something that wasnt just useful, but also super cool! Thats why I went with creating my own expansion support instead of just adding a USB hub and calling it a day.
