From the project

Ensemble de systèmes pour l'arrosage du jardin

Ce sont des cartes esclaves permettant de piloter pompes et oyas.

Design initial à base de modules arduino nano. Gestion des pompes et des oyas avec la même carte. Les premières cartes comportaient un module RS485 indépendant. Il a ensuite été intégré sur la carte mère. Ces cartes sont alimentées par le régulateur du module nano. Il y'a eu plusieurs versions de cette "première" carte.
