Questions
How big is the EE1 project PCB?
It measures 50 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the EE1 project use?
33 parts, built around the LM358. 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 EE1 project KiCad files?
From the Mr-Bossman/resistor_code_breaker repository on GitHub, at the commit this page was made from: the board is EE1_project.kicad_pcb and its schematic EE1_project.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the EE1 project design in my own project?
Its repository states no licence, so its author keeps all rights: ask Mr-Bossman before reusing the design.
