Questions
How big is the FeedbackProject PCB?
It measures 54 × 44.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FeedbackProject use?
17 parts, built around the AD8220ARM, L293D, BZX55C2V4 and DMG1012UW-7-VB. 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 FeedbackProject KiCad files?
From the std010/ECAD_my_main_project repository on GitHub, at the commit this page was made from: the board is feedbackProject/feedbackProject.kicad_pcb and its schematic feedbackProject/feedbackProject.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FeedbackProject design in my own project?
Its repository states no licence, so its author keeps all rights: ask std010 before reusing the design.
