Questions
How big is the DymBOX AVR PCB?
It measures 70.2 × 144.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DymBOX AVR use?
49 parts, built around the ATMEGA8A-PU, DS18B20, L7805 and BC327. 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 DymBOX AVR KiCad files?
From the 2pkstartup/dymbox_pcb repository on GitHub, at the commit this page was made from: the board is DymBOX_AVR.kicad_pcb and its schematic DymBOX_AVR.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DymBOX AVR design in my own project?
Its repository states no licence, so its author keeps all rights: ask 2pkstartup before reusing the design.
