Questions
How big is the Ece49022-interface PCB?
It measures 60.2 × 52.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Ece49022-interface use?
40 parts, built around the TPS54202DDCT, DMN3200U-7-VB, KSC1815YTA and PS1240P02BT. 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 Ece49022-interface KiCad files?
From the jjagani/ECE49022_hardware repository on GitHub, at the commit this page was made from: the board is pcb/ece49022-interface/ece49022-interface.kicad_pcb and its schematic pcb/ece49022-interface/buzzerdriver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ece49022-interface design in my own project?
Its repository states no licence, so its author keeps all rights: ask jjagani before reusing the design.
