Carte1
About the Carte1 PCB
Carte1 is an open source PCB design by Honzaaa45, published on GitHub under the MIT license. It is a 4-layer board measuring 170.6 × 126.1 mm, with 40 components from 8 distinct parts.
Other key parts include the MCP23017, Output, Input and BOB-09056. By type, the board carries 14 ICs, 13 resistors, 12 capacitors and 1 connector.
From the project
Testeur de câbles industriel 40+40 broches — ESP32 + LVGL + KiCad + Fusion 360. Projet fil rouge BUT2 GEII AII pour MSL Circuits.
Testeur de câbles industriel 40+40 broches, portable, à base d'ESP32 + LVGL.
Le problème : chez MSL Circuits, le contrôle qualité des câbles en fin de fabrication reposait sur un test manuel au multimètre — long, fastidieux, sujet à l'erreur humaine. Les testeurs pros du marché coûtent 3 000 à 15 000 €.
La solution : un testeur portable, batterie 8 h, 40+40 broches, modulaire via adaptateurs (RJ45, USB, SUB-D, Molex, TE), qui détecte en < 1 seconde continuité, courts-circuits, inversions et fils coupés — et affiche une résistance approximative après calibration. Coût matière : ~80 €.
