Questions
How big is the GradientDriver PCB?
It measures 54.6 × 67.9 mm and has 4 copper layers, 1.6 mm thick.
What parts does the GradientDriver use?
61 parts, built around the OPA548TG3, AD8421BRZ, AD8603AUJ and OP37GSZ-REEL7. 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_rev2/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.
