Questions
How big is the Testing shield PCB?
It measures 79.5 × 58.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Testing shield use?
32 parts, built around the PCF8574T. 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 Testing shield KiCad files?
From the maribu/boards repository on GitHub, at the commit this page was made from: the board is testing-shield/testing-shield.kicad_pcb and its schematic atmega1284p/atmega1284p.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Testing shield design in my own project?
Its repository states no licence, so its author keeps all rights: ask maribu before reusing the design.
