About the RainGauge ST Morpho Shield V1.2

RainGauge ST Morpho Shield V1.2 is an open source PCB design by alexandreberg, published on GitHub under the AGPL-3.0 license. It is a 2-layer board measuring 84 × 84.5 mm, with 47 components from 34 distinct parts.

Other key parts include the TIL113, CD4040, 74HC166, BMP-280 and BP_Pwr_3v3. By type, the board carries 10 connectors, 9 capacitors, 7 ICs, 7 jumpers, 7 resistors and 3 test points.

It belongs with the rf & radio, iot & wireless and sensors designs in this gallery.

From the project

Open-source flood early warning system: LoRa water-level and rain stations, gateway, web dashboard and LightGBM/MLR forecasts. Master's dissertation (IFSC, Brazil).

KiCad 9 projects of the two custom shields used by the SAPI stations. Both are fabrication-ready (gerbers in gerbertoorder/) and licensed under CERN-OHL-S-2.0.

The 3D models (.step, .stp, .stl, .wrl, and zipped models) are stored in Git LFS, ~0.9 GB in total. To clone without them:

KiCad opens the projects without the models; only the 3D viewer needs them. Each release also has the complete project, models included, as a .tar.gz attachment.
