Gravity: LoRaWAN Node Module (US915) – SX1262-Based, 4.5km Range for IoT & Agriculture

This module is a compact, easy-to-integrate wireless communication solution tailored for long-distance, low-power outdoor IoT scenarios. Based on the SX1262 chip and LoRa modulation technology, it operates in the US915 frequency band, also applicable to EU868 in other versions, and supports both LoRa point-to-point and LoRaWAN networking. With an effective urban transmission range of up to 1.5 kilometers and 4.5 kilometers in open environments, it enables reliable, wide-area data transmission without the need for traditional wired infrastructure. Ideal for agriculture, environmental monitoring, and industrial sensing projects.

The module supports dual communication modes with both LoRa and LoRaWAN. It caters to various deployment needs, whether direct module-to-module communication or integration with cloud platforms like TTN or ChirpStack via LoRaWAN gateways. Its versatility is evident in its capacity for one-to-one, one-to-many, and many-to-one point-to-point communication, as well as bridge transmission, making it adaptable for multiple configurations.

Designed for outdoor environments, its long-distance wireless transmission is noteworthy, providing up to 1.5 km of range in urban settings and up to 4.5 km in open spaces. This feature makes it ideal for scenarios where traditional Wi-Fi or 4G networks are unavailable or insufficient due to their power demands. Its application thrives in enabling connectivity for remote agricultural plots, expansive industrial sites, or isolated environmental monitoring stations.

Integrating this module is straightforward, given its built-in LoRa/LoRaWAN protocol stack, removing the need for intensive low-level development. It seamlessly supports Arduino IDE, Mind+, and MakeCode graphical programming, and interfaces like I2C/UART make it compatible with microcontrollers such as micro:bit, Arduino, and ESP32. This ensures not only quick integration but also a low learning curve for IoT developers and educators aiming for rapid prototyping and deployment.
