About the Irrgiation sensor rev4-3 PCB

Irrgiation sensor rev4-3 is an open source STM32 PCB design by henriheimann, published on GitHub. It is a 2-layer board measuring 180 × 38 mm, with 35 components from 24 distinct parts.

Its main chip is the STM32L412KB, from the STM32 family. Other key parts include the 24LC32, RFM95W and TLV61225. By type, the board carries 11 capacitors, 8 resistors, 4 ICs, 2 transistors, 2 connectors and 2 inductors.

It belongs with the sensors designs in this gallery, and the repository also holds 3 earlier revisions of it.

From the project

Repository of the Prosper III Environment Monitor project ☀️🌱

This repository contains the source code accompanying my master's thesis "Entwicklung einer digitalen Lösung zur Unterstützung von Tactical Urbanism auf Prosper III" (Development of a Digital Solution to Support Tactical Urbanism on Prosper III) at Hochschule Ruhr West. It includes hardware designs and embedded software for LoRaWAN-based sensor nodes to collect microclimate and irrigation data, as well as a web application and infrastructure to manage sensor nodes and view data.

Irrgiation sensor rev4-3: common questions

What microcontroller does the Irrgiation sensor rev4-3 use?

The Irrgiation sensor rev4-3 is built around the STM32L412KB, from the STM32 family.

How big is the Irrgiation sensor rev4-3 PCB?

The Irrgiation sensor rev4-3 measures 180 × 38 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Irrgiation sensor rev4-3?

35 components, from 24 distinct parts. The full bill of materials is listed on this page.

Where can I download the Irrgiation sensor rev4-3 design files?

From the henriheimann/prosper3-monitor repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Irrgiation sensor rev4-3 design in my own project?

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

Can I test firmware for the Irrgiation sensor rev4-3 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
