Unit LoRaWAN-US915

SKU: U184-US915

Description

Unit LoRaWAN-US915 is a LoRaWAN communication module based on LoRa technology, specifically designed for the US915 frequency band, suitable for the United States and other regions using the US915 frequency band. The module adopts the STM32WLE5 solution, supporting long-distance communication with low power consumption and high sensitivity. The module comes with a built-in LoRaWAN protocol stack, supporting Class A, Class B, and Class C operation modes. It also supports point-to-point (P2P) communication mode and uses a UART communication interface (controlled via AT commands) for flexible configuration. Additionally, the product features a high-performance rubber duck antenna, optimized for stable signal coverage and extended communication range, making it suitable for various complex environments. This module can be used as a collection node to connect to a gateway for data collection and management, or for direct communication between devices in scenarios where a gateway is not required. It is widely used in IoT communication scenarios such as smart agriculture, industrial monitoring, and environmental monitoring node deployment, where long-distance and low-power communication is essential.
