Gravity: LoRaWAN Node Module (EU868) SX1262 Based, 4km Range for IoT & Agriculture
The Gravity LoRaWAN Node Module (EU868) is a high-performance wireless communication solution designed for long-range, low-power IoT deployments in outdoor and remote environments. Built on the SX1262 RF transceiver and LoRa modulation technology, it operates in the EU868 frequency band used across Europe and other compatible regions. The module supports both LoRa point-to-point (P2P) communication and LoRaWAN networking, offering flexibility for diverse network architectures. With reliable communication ranges of up to 1.2 kilometres in urban areas and up to 4 kilometres in open spaces, this module is well suited for agriculture sensor networks, environmental monitoring systems, and smart outdoor IoT applications requiring stable, energy-efficient data transmission.

Dual Communication Modes: LoRa & LoRaWAN
The module supports flexible switching between LoRa P2P and LoRaWAN protocols.
- In LoRa mode, it supports direct one-to-one, one-to-many, many-to-one, and bridge communication.
- In LoRaWAN mode, it supports both Class A and Class C operation and can be incorporated into networks such as The Things Network (TTN) and ChirpStack via ABP or OTAA activation techniques.
Reliable Long-Range Transmission
Equipped with an onboard PCB antenna and LoRa technology, the module provides:
- 1.2 km effective range in urban areas.
- 4 km effective range in open areas: The module provides consistent and dependable connection across broad outside regions, exceeding the power consumption and range limits of WiFi and 4G.
Low Power Consumption, Ideal for Battery-Powered Nodes
LoRa modulation technology enables ultra-low power operation, considerably increasing the battery life of distant sensor nodes when compared to WiFi or cellular-based solutions, making it ideal for long-term deployment in power-constrained applications.
Plug-and-Play with Wide Compatibility
No low-level protocol development is necessary. The module includes a full LoRa/LoRaWAN protocol stack and supports the Arduino IDE, Mind+, and MakeCode graphical programming environments.
- Compatible with the micro:bit, Arduino, ESP32, and other 3.3V/5V development boards.
- Standard I2C and UART interfaces make device integration easier.
DFRobot LoRaWAN Series
The DFRobot LoRaWAN product series focuses on "simplified development and efficient deployment," addressing situations such as learning, development, testing, and deployment while also providing developers with comprehensive low-power wide-area network (LPWAN) solutions.
