Questions
How big is the Current Controller PCB?
It measures 113.7 × 83.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Current Controller use?
92 parts, built around the DCWN03B-15, OP37GSZ-REEL7, AD8421BRZ and LM324. 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 Current Controller KiCad files?
From the xecus/opensource-mri-project repository on GitHub, at the commit this page was made from: the board is PCB/Current_Controller/Current_Controller.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Current Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask xecus before reusing the design.
