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-range communication with low power consumption and high sensitivity characteristics. The module integrates the LoRaWAN protocol stack and supports three operating modes: Class A, Class B, and Class C. It also supports point-to-point (P2P) communication mode and uses a UART communication interface (controlled by the AT command set) for flexible configuration. Additionally, the product features a high-performance rubber antenna, with an optimized antenna design that provides more stable signal coverage and longer communication distance, making it suitable for various complex environments. The module can be used as a data collection node to connect to a gateway for data collection and management, or it can enable direct communication between devices in scenarios where no gateway is needed. It is widely used in long-range, low-power IoT communication scenarios, such as smart agriculture, industrial monitoring, and environmental monitoring node deployments.
