The LR1302 module is a next-generation LoRaWAN gateway module featuring a mini-PCIe form factor designed for low power consumption and high-performance reliability. Based on the advanced Semtech SX1302 LoRaWAN baseband chip, this module enables gateway products to achieve massive potential for long-distance wireless transmission. Compared to legacy SX1301 and SX1308 chips, the SX1302 chip delivers higher sensitivity, reduced power consumption, and lower operating temperatures. It supports 8-channel data transmission, significantly enhancing communication efficiency and network capacity for large-scale device connectivity.
The module reserves two antenna interfaces: one dedicated to transmitting and receiving LoRa signals, and an additional U.FL (IPEX) interface for independent transmission. To ensure a stable communication environment, it is equipped with a metal shield that protects against external electromagnetic interference.
The LR1302 LoRaWAN gateway module is available in both SPI and USB versions, supporting the US915 and EU868 frequency bands. This provides users with flexible regional frequency solutions tailored to their specific deployment needs.
Specifically engineered for the IoT (Internet of Things) ecosystem, the LR1302 is ideal for diverse applications. Whether deployed in smart cities, smart agriculture, industrial automation, or remote monitoring, the LR1302 module provides a reliable connection and efficient data throughput.
Application Example
Note: Package does not include Raspberry Pi, GPS, Gateway HAT, IPEX cables, or antennas.
