Questions
How big is the Geiger EDW PCB?
It measures 120.1 × 46 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Geiger EDW use?
60 parts, built around the ATMEGA8L-8AU, MAX649CPA, MC34063AD and LTV-356T. 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 Geiger EDW KiCad files?
From the Sidolux/geiger_counter repository on GitHub, at the commit this page was made from: the board is PCB_SCH/Geiger_EDW.kicad_pcb and its schematic PCB_SCH/Geiger_EDW.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Geiger EDW design in my own project?
Its repository states no licence, so its author keeps all rights: ask Sidolux before reusing the design.
