Questions
How big is the OxygenF7 PCB?
It measures 74 × 45 mm and has 2 copper layers, 1.6 mm thick.
What parts does the OxygenF7 use?
65 parts, built around the BMP388, W25Q128JVSIQ, MPU-6000 and XC6220B331MR. 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 OxygenF7 KiCad files?
From the iBelieve/oxygen repository on GitHub, at the commit this page was made from: the board is hardware/OxygenF7.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the OxygenF7 design in my own project?
Its repository states no licence, so its author keeps all rights: ask iBelieve before reusing the design.
