Overview
Badge is an open-source printed circuit board by OpenBadgeProject, from the OpenBadgeProject/badge-hardware repository on GitHub, published under the Apache-2.0 licence. It is a 2-layer board of 76.2 × 114.3 mm with 37 parts on 56 nets, routed with 302 tracks and 0 vias.
It is built around the ATTINY85-20PU, 74HC595 and TL3315NF160Q, with the BS-7 among its other parts. Its parts include 16 resistors, 6 switches and 4 ICs. It belongs with the lEDs and displays boards and the AVR (ATmega, ATtiny) boards of this library.

README
README.mdOpen Badge Project - Surface Mount Version
This is the Open Badge Project hardware repository.
There are two badge designs in this repo. The surface-mount directory holds the surface mount badge design. The production subdirectory contains the BOM and position data files.
The through-hole directory is for the through hole badge material. There is no BOM or pick and place spreadsheet. There's no reason you couldn't do that, but it was designed for humans to solder.

Questions
How big is the Badge PCB?
It measures 76.2 × 114.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Badge use?
37 parts, built around the ATTINY85-20PU, 74HC595, TL3315NF160Q and BS-7. 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 OpenBadgeProject/badge-hardware repository on GitHub, at the commit this page was made from: the board is through-hole/kicad/badge.kicad_pcb and its schematic surface-mount/kicad/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 publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
