Overview
Badge is an open-source printed circuit board by ZIZO932, from the ZIZO932/SNAKE-PCB- repository on GitHub. It is a 2-layer board of 71.3 × 88.9 mm with 16 parts on 10 nets, routed with 93 tracks and 10 vias.
Its parts include 3 resistors, 3 transistors, 2 diodes, 1 connector and 1 switch. It belongs with the lEDs and displays boards of this library.
README
README.mdSnake PCB
A snake-shaped detector board I designed in KiCad. The coil is its tongue, the two LEDs are its eyes, and a small vibration motor sits near the tail.
The circuit uses a coil and three NPN transistors to pick up a nearby signal and drive the LEDs and motor. I liked the idea of making the board shape part of the project instead of putting everything on a rectangle.

Questions
How big is the Badge PCB?
It measures 71.3 × 88.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Badge use?
16 parts. 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 Badge KiCad files?
From the ZIZO932/SNAKE-PCB- repository on GitHub, at the commit this page was made from: the board is badge.kicad_pcb and its schematic badge.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Badge design in my own project?
Its repository states no licence, so its author keeps all rights: ask ZIZO932 before reusing the design.
