Introduction
Ce repo a été réalisé dans le cadre d'un stage de 4ème année d'école d'ingénieurs à l'École de Technologie Supérieure (ÉTS) de Montréal, au sein du laboratoire LACIME, par un étudiant de Polytech Grenoble. Si vous souhaitez avoir plus de détails sur le contenu de chaque projet merci de suivre les dossier projet_batterie et projet_salle_blanche. Le dossier contient aussi tous les fichiers Kicad, Le dossier Kicad contient les évolutions des différentes cartes produites et la dernière version est celle à jour pour le projet batterie. Le dossier Kicad esp maitre est le dossier principale pour le projet salle blanche.

Questions
How big is the Stage4A PCB?
It measures 75 × 119.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Stage4A use?
65 parts, built around the INA237AIDGSR, ISOM8600DFGR and MCP23017-E/SO. 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 Stage4A KiCad files?
From the maxgr2/stage4A repository on GitHub, at the commit this page was made from: the board is Kicad/V6/V6/V6.kicad_pcb and its schematic Kicad/V1_cartebis/Temp_board_ajout.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stage4A design in my own project?
Its repository states no licence, so its author keeps all rights: ask maxgr2 before reusing the design.
