RGB Beacon
The RGB Beacon is a small hackable RGB LED based on the ATTiny13a. In addition to a undeniably funky LED, the beacon also integrate a tactile switch and a potentiometer for even more goodness.
Hardware
Bill of materials
The MCU inside the Beacon is a ATTiny13a clocked at 9.6MHz using the onboard oscillator.
The RGB LED is the common anode ASMB-MTB1-0A3A2.

Questions
What parts does the RGB LED use?
19 parts, built around the ATTINY13A-SSU and MMBT3904. 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 RGB LED KiCad files?
From the Bindless-Chicken/RGB-Beacon repository on GitHub, at the commit this page was made from: the board is Hardware/RGB_LED.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the RGB LED design in my own project?
Its repository states no licence, so its author keeps all rights: ask Bindless-Chicken before reusing the design.
