Questions

How big is the Open PCB?

It measures 126.4 × 112 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Open use?

127 parts, built around the STM32F103CXTX and CD74HC4067SM96. 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 Open KiCad files?

From the senrobo/open repository on GitHub, at the commit this page was made from: the board is l1/l1.kicad_pcb and its schematic breakout/Cam Adapter/Cam Adapter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Open design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
