/!\ Projet en cours de développement vers une verssion stable et correctement doccumentée /!\
Commencé dans le cadre d'un mois de découverte de l'électronique, ce projet consiste en une calculatrice avec notation en polonaise inversse dont le hardware est propice à la découverte et l'initiation à l'électronique, soit:
- Montage
- Développement
- Mesures & Dépannage
- Programation
Basée sur ESP32 et dévelopée sur un firware Micropython, elle est propice à une compréhenssion de sa structure fondamentale et à des réalisations pratique très rapidement

Questions
How big is the Projet PCB?
It measures 98 × 187 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Projet use?
137 parts, built around the ESP32-WROOM-32, PCF8574AP, FT232RL and BC856B. 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 Projet KiCad files?
From the FranklinBerger/Polonise-Inverse repository on GitHub, at the commit this page was made from: the board is 4_Fabrication/Version_0.1/C_KiCad_430476043716/projet.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Projet design in my own project?
Its repository states no licence, so its author keeps all rights: ask FranklinBerger before reusing the design.
