Questions
How big is the Current Source PCB?
It measures 50 × 20 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Current Source use?
24 parts, built around the AD8566ARMZ-REEL, TIP120 and LTR50UZPFLR360. 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 Source KiCad files?
From the davidphamthecat/PCBs repository on GitHub, at the commit this page was made from: the board is URECA/Current Source/Current Source.kicad_pcb and its schematic Mecatron 2027/6S Battery Protector/6S Battery Protector.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Current Source design in my own project?
Its repository states no licence, so its author keeps all rights: ask davidphamthecat before reusing the design.
