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 will cost a fortune.
Under the Hardware folder you will finde besides the project files also the PDF files for the boards schematic.
For more information and the motivation also to share the KiCad files with you have a look at https://www.elektormagazine.com/labs/lorawan-node-experimental-platform If you are new to KiCad and like to modify the PCB on your own, fell free , and if you need a good book to start with KiCad have a look at: https://www.elektor.com/kicad-like-a-pro
Grab a copy of KiCad and download the repository, or just garb the schematics to get an idea of the board. For the software grab a copy of the Arduino IDE and install the STM32 core support for Arduino ( https://github.com/stm32duino/Arduino_Core_STM32 ) You can use the exelente guide provide here : https://github.com/stm32duino/Arduino_Core_STM32#getting-started
