Questions
How big is the GradientDriver PCB?
It measures 73.7 × 70.6 mm and has 4 copper layers, 1.6 mm thick.
What parts does the GradientDriver use?
61 parts, built around the AD8603AUJ, AD8421BRZ, D44H11 and L7812. 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 GradientDriver KiCad files?
From the xecus/opensource-mri-project repository on GitHub, at the commit this page was made from: the board is PCB/GradientDriver/GradientDriver.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the GradientDriver design in my own project?
Its repository states no licence, so its author keeps all rights: ask xecus before reusing the design.
