Questions
How big is the Medicool PCB?
It measures 71.5 × 81.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Medicool use?
37 parts, built around the LM2596T-5.0. 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 Medicool KiCad files?
From the pranaykpradeep/medicool repository on GitHub, at the commit this page was made from: the board is MEDICOOL_pcb/MEDICOOL.kicad_pcb and its schematic MEDICOOL_pcb/MEDICOOL.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Medicool design in my own project?
Its repository states no licence, so its author keeps all rights: ask pranaykpradeep before reusing the design.
