Questions

How big is the DevBoard PCB?

It measures 100 × 83.4 mm and has 4 copper layers, 1.6 mm thick.

What parts does the DevBoard use?

131 parts, built around the MCP6004-E/P, TL072, LM1117-3.3 and LM1117-5.0. 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 DevBoard KiCad files?

From the dchwebb/DevBoard repository on GitHub, at the commit this page was made from: the board is DevBoard.kicad_pcb and its schematic Base_Controls.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the DevBoard design in my own project?

Its repository states no licence, so its author keeps all rights: ask dchwebb before reusing the design.
