Questions
How big is the UNLaM duino PCB?
It measures 69.5 × 103.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the UNLaM duino use?
49 parts, built around the ATMEGA328-PU and LM2576WT. 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 UNLaM duino KiCad files?
From the LacieUnlam/UNLaM-duino repository on GitHub, at the commit this page was made from: the board is pcb/unlamduino/unlamduino.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the UNLaM duino design in my own project?
Its repository states no licence, so its author keeps all rights: ask LacieUnlam before reusing the design.
