Features
- 2 super attractive neopixel eyes
- A tiny buzzer to annoy all your friends
- A whopping 4096kB of flash storage space
- Dual power source options, USB-C or CR2023 battery
- Hidden programs to unlock by being social in meatspace (just ask the authors how!)
- Ability to reprogram via a UPDI programmer
Usage/Examples
Normal Operation
Insert a CR2032 battery into the holder or plug into a usb-c power supply capable of supplying 5volts. Patterns will start automatically and the device will goto sleep after 10 minutes.
Highpower Mode
Hold in the headpat button while powering on. This will increase the LED brightness and disable the sleep functionality.
Lessons Learned
- 4096kB of flash is a tiny amount
- CR2032 batteries are terrible

Questions
How big is the BadgeKittyv2 PCB?
It measures 50.8 × 53.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the BadgeKittyv2 use?
32 parts, built around the SD0805S040S0R5, BAT-HLD-001, DFE201612E-2R2M=P2 and KLJ-5030. 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 BadgeKittyv2 KiCad files?
From the Fuse-Technical-Group/BadgeKitty repository on GitHub, at the commit this page was made from: the board is hardware/KiCad Project/BadgeKittyv2/BadgeKittyv2.kicad_pcb and its schematic hardware/KiCad Project/BadgeKittyv2/BadgeKittyv2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BadgeKittyv2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Fuse-Technical-Group before reusing the design.
