Questions
How big is the MRIRobot PCB PCB?
It measures 172 × 99 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MRIRobot PCB use?
126 parts, built around the ADS7830IPW, FT231XS-R, LM22676MR-5.0 and LM22676MR-ADJ. 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 MRIRobot PCB KiCad files?
From the naichenzhao/pressure repository on GitHub, at the commit this page was made from: the board is MRIRobot_PCB.kicad_pcb and its schematic MRIRobot_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MRIRobot PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask naichenzhao before reusing the design.
