About the Jard c3 PCB

Jard c3 is an open source ESP32 PCB design by bpmine, published on GitHub. It is a 2-layer board measuring 78 × 78 mm, with 33 components from 20 distinct parts.

Its main chip is the ESP32-C3_SUPERMINI_TH, from the ESP32 family. Other key parts include the BPC_Alim3_3V. By type, the board carries 12 resistors, 9 diodes, 7 capacitors, 2 ICs, 2 connectors and 1 transistor.

It belongs with the iot & wireless designs in this gallery.

From the project

Ensemble de systèmes pour l'arrosage du jardin

Nous avons 4 cuves pour une capacité totale de 2200 L.

- Cuve principale de 1000 L - cuve "Paul" de 300 L - cuve "Réduit" de 520 L - cuve "Barbec" de 520 L

Deux cuves de 520 L et une de 300 L alimentent nos deux systèmes de remplissage automatique des OYAs.

Les cuves sont communicantes et un système permet de pomper l'eau de la cuve principale vers les autres.

Cette cuve recueille l'eau du toit de la maison. D'une capacité de 1000 L, elle constitue la réserve principale. Elle sert à alimenter la cuve "Paul" et aussi la cuve "Réduit" en cas de besoin.

Jard c3: common questions

What microcontroller does the Jard c3 use?

The Jard c3 is built around the ESP32-C3_SUPERMINI_TH, from the ESP32 family.

How big is the Jard c3 PCB?

The Jard c3 measures 78 × 78 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Jard c3?

33 components, from 20 distinct parts. The full bill of materials is listed on this page.

Where can I download the Jard c3 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 Jard c3 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 Jard c3 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
