README
README.mdSkye - your cute microcontroller
Are you looking for a flashy microcontroller as a keychain, but don't want to hang an Arduino? Or are you in need of a tiny microcontroller to put in your next project? Or, want to show off your coding skills but don't want to buy an RGB LED and resistors? Need somthing portable for your next VUSB hack?
Skye is the tiny microcontroller for the casual. With a small form factor, a WS2812B LED and a low price, Skye is the cutest microcontroller you'll ever own.
Features:
- WS2812B
- It's a keychain!
- Minimalistic top surface
- Breadboard-friendly headers
- Smaller than many USB sticks
- But it's a keychain!
Specifications:
- ATtiny85
- Sized at 12.7mm by 24.4mm
- 6 IO pins
- 5V and GND pins (if you want to power it with an external power source, you can connect it with the included 5V regulator)
- Runs the micronucleus bootloader!

Questions
How big is the Skye PCB?
It measures 13.2 × 24.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Skye use?
14 parts, built around the WS2812 and MBR0520L-TP. 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 Skye KiCad files?
From the serverwentdown/Skye repository on GitHub, at the commit this page was made from: the board is hardware/skye.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Skye design in my own project?
Its repository states no licence, so its author keeps all rights: ask serverwentdown before reusing the design.
