This is my submission to Hack Club Pendant YSWS!
I designed a small board with a rotary encoder, 2 push-buttons, 2 RGB LEDs, an OLED screen and a XIAO ESP32! It can be used for games, internet tasks with web APIs, Home Assistant control and more!
For part details, see the BOM. To learn about how I designed this, check out the journal!

Questions
How big is the Pendant PCB?
It measures 35.5 × 51 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pendant use?
11 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 Pendant KiCad files?
From the duckida/pendant repository on GitHub, at the commit this page was made from: the board is pendant.kicad_pcb and its schematic pendant.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pendant design in my own project?
Its repository states no licence, so its author keeps all rights: ask duckida before reusing the design.
