Questions
How big is the LaserDriverTest PCB?
It measures 57.2 × 38.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LaserDriverTest use?
10 parts, built around the AD5293BRUZ-20. 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 LaserDriverTest KiCad files?
From the kemerelab/ConstantCurrent repository on GitHub, at the commit this page was made from: the board is LaserDriverTest/LaserDriverTest.kicad_pcb and its schematic LaserDriverTest/LaserDriverTest.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LaserDriverTest design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
