Unit LoRaWAN-AS923

SKU:U184-AS923

Description

Unit LoRaWAN-AS923 is a LoRaWAN communication module based on LoRa technology, specifically designed for the AS923 frequency band, suitable for Asia and other regions using the AS923 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, with an optimized antenna structure design, providing more stable signal coverage and longer communication distances, 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 long-range, low-power IoT communication scenarios such as smart agriculture, industrial monitoring, and environmental monitoring node deployment.
