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.

Esclave OYA M0: common questions

What microcontroller does the Esclave OYA M0 use?

The Esclave OYA M0 is built around the ATSAMD21G18A-A, from the Microchip SAM family.

How big is the Esclave OYA M0 PCB?

The Esclave OYA M0 measures 78.6 × 30 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esclave OYA M0?

58 components, from 33 distinct parts. The full bill of materials is listed on this page.

Where can I download the Esclave OYA M0 design files?

From the bpmine/jarduino repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Esclave OYA M0 design in my own project?

The repository has no license, so all rights stay with bpmine. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Esclave OYA M0 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Microchip SAM firmware against it before you order a PCB.
