Questions
How big is the Pami PCB?
It measures 76 × 68 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pami use?
44 parts, built around the R-78E5.0-1.0, LM3940IMP-3.3, PMEG2010AEH and SC0918. 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 Pami KiCad files?
From the ENACRobotique/PAMIS repository on GitHub, at the commit this page was made from: the board is 2025/carte_elec/pami.kicad_pcb and its schematic 2024/carte_pami/carte_pami.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pami design in my own project?
Its repository states no licence, so its author keeps all rights: ask ENACRobotique before reusing the design.
