Questions
How big is the Eps PCB?
It measures 90 × 96 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Eps use?
54 parts, built around the CMSH3-40MA, LT3652IMSE#PBF and MBR340. 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 Eps KiCad files?
From the prasannan-robots/eps repository on GitHub, at the commit this page was made from: the board is eps.kicad_pcb and its schematic batterycharger.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Eps design in my own project?
Its repository states no licence, so its author keeps all rights: ask prasannan-robots before reusing the design.
