About the SAPI LoRa Arduino Shield V1.0

SAPI LoRa Arduino Shield V1.0 is an open source PCB design by alexandreberg, published on GitHub under the AGPL-3.0 license. It is a 2-layer board measuring 68.6 × 53.3 mm, with 20 components from 19 distinct parts.

Other key parts include the RFM69HW. By type, the board carries 5 connectors, 2 ICs, 2 jumpers, 2 switches, 1 antenna and 1 diode.

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.
