Questions
How big is the GreHack2019-V2 PCB?
It measures 89.7 × 97.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the GreHack2019-V2 use?
29 parts, built around the ATTINY85-15M, 24LC16B/P and BSS138. 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 GreHack2019-V2 KiCad files?
From the GreHack/CTF-challs repository on GitHub, at the commit this page was made from: the board is 2019/Hardware/PCB/Main/GreHack2019-V2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the GreHack2019-V2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask GreHack before reusing the design.
