This has been made with a very hot needle in a very short timeframe.
PCB design is suboptimal.
It is based on the WCH CH32V003 MCU and draws between 11mA and 14mA at 5V.
Programming
To flash the badge, you need to have a WCH-LinkE programmer and the
wlink CLI tool.
NOTE: The older WCH-Link (without E) does not work!
Connect as follows:
TP3is the SWDIO pinTP1is 5V VCCTP2is GND (ground)

Questions
How big is the Hackoween badge PCB?
It measures 88.5 × 44.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackoween badge use?
19 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 Hackoween badge KiCad files?
From the rappet/hackoween-badge repository on GitHub, at the commit this page was made from: the board is hackoween-badge.kicad_pcb and its schematic hackoween-badge.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hackoween badge design in my own project?
Its repository states no licence, so its author keeps all rights: ask rappet before reusing the design.
