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.
Dual Communication Modes: LoRa & LoRaWAN
Supports both LoRa point-to-point communication (one-to-one, one-to-many, many-to-one, and bridge transmission) and LoRaWAN networking (Class A and Class C). This dual-mode design offers flexible deployment options—whether for direct module-to-module communication or integration with cloud platforms like TTN or ChirpStack via LoRaWAN gateways.
Kilometer-Range Wireless Transmission
Designed for outdoor environments, the module delivers reliable long-distance performance: up to 1.5 km in urban settings and up to 4.5 km in open areas. This makes it suitable for use cases where Wi-Fi or 4G coverage is limited or too power-hungry.
Quick Integration and Low Learning Curve
Features built-in LoRa/LoRaWAN protocol stack—no need for low-level development. Supports Arduino IDE, Mind+, and MakeCode graphical programming, and offers I2C/UART interfaces compatible with popular platforms like micro:bit, Arduino, and ESP32. Enables seamless integration and rapid prototyping for IoT developers and educators alike.
