SparkFun offers two versions of the Digi X-ON LoRaWAN development kit for regional compatibility: one for North America and one for Europe. The main difference between the two is the radio frequencies (LoRaWAN and cellular), which are designed to comply with the regional regulations in each area. All other hardware and software features are essentially the same across both kits.

ENS160 and BME280 Environmental Sensor Combo

The SparkFunDigi X-ON LoRaWAN development kit supports a variety of software and tools for development, configuration, and remote management. The Digi X-ON Cloud enables secure device provisioning, real-time data visualization, and OTA firmware updates, while Digi Remote Manager (DRM) provides gateway diagnostics and security policy management. The HX15 gateway runs Digi Embedded Yocto Linux on the STM32MP157C MPU.

The SparkFun IoT Node for LoRaWAN can be programmed with the Arduino IDE, MicroPython, and the Raspberry Pi Pico SDK (C/C++), which includes libraries for LoRaWAN. Digi XCTU simplifies module configuration, and The Things Stack (TTS) offers an alternative open-source network server. Developers can also log and visualize sensor data using Qwiic Python libraries, Grafana, or Node-RED, while security is managed through Mbed TLS, MQTT, and HTTP APIs.

The Digi X-ON Kit North America and Europe models are both available for pre-order for $395 on the SparkFun store. For more details about the product, you can visit the individual product pages and documentation for the Digi HX15 Gateway, the SparkFun IoT Node for LoRaWAN, and the ENS160/BME280 environmental sensor.
