Files for the Elektor LoRaWAN Node Experimental Platform

This is the hardware and software repository for the Elektor LoRa node. This is open hardware under the CERN OHL v1.2, so feel free to grab your copy and have fun. Also this project is done with KiCad, so you can have a look at the files without software that costs a fortune.

Under the Hardware folder you will find (besides the project files) the PDF files for the board schematics.
