Questions
How big is the Led driver PCB?
It measures 67.3 × 33 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Led driver use?
11 parts. 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 Led driver KiCad files?
From the eulerlab/open-visual-stimulator repository on GitHub, at the commit this page was made from: the board is boards/mosfet_circuit/led_driver.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Led driver design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
