Questions
How big is the Dev board 1 PCB?
It measures 91.5 × 93.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dev board 1 use?
76 parts, built around the MT48LC16M16A2TG and BAT54C. 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 Dev board 1 KiCad files?
From the Delete228/OpenCalc repository on GitHub, at the commit this page was made from: the board is pcb/dev_board_1/dev_board_1.kicad_pcb and its schematic keyboard/pcb/keyboard/keyboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dev board 1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Delete228 before reusing the design.
