Description
This project is a simple PCB design using the Digistump ATtiny microcontroller, developed as part of the Soldiers Hack Club. The board is intended for beginner-level electronics projects and uses KiCad 7 for design. It includes both manually routed and auto-routed layouts to compare routing methods.

Questions
How big is the Digistump ATtiny PCB?
It measures 37.8 × 12 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Digistump ATtiny use?
11 parts, built around the ATTINY85-15M. 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 Digistump ATtiny KiCad files?
From the Hasona57/Digistump-ATtiny repository on GitHub, at the commit this page was made from: the board is PCB/Digistump ATtiny.kicad_pcb and its schematic PCB/Digistump ATtiny.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Digistump ATtiny design in my own project?
Its repository states no licence, so its author keeps all rights: ask Hasona57 before reusing the design.
