Questions
How big is the Day2tasks PCB?
It measures 125.5 × 77 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Day2tasks use?
8 parts, built around the ARDUINO UNO R3. 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 Day2tasks KiCad files?
From the unm-rs/pcb-workshop-robot repository on GitHub, at the commit this page was made from: the board is Day 2/KiCad Project Files/day2tasks.kicad_pcb and its schematic Day 2/KiCad Project Files/day2tasks.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Day2tasks design in my own project?
Its repository states no licence, so its author keeps all rights: ask unm-rs before reusing the design.
