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 (902-928MHz) frequency band. The module adopts the STM32WLE5 solution, supporting long-range communication with low power consumption and high sensitivity . 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 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. Complies with LoRaWAN 1.0.3 protocol Supports AS923 frequency band Supports LoRa P2P (Point-to-Point) communication LoRaWAN activation modes: OTAA, ABP Serial communication (AT commands) Uses high-sensitivity rubber stick antenna Low power consumption Compatible with for holes Development platforms: for UIFlow 1.0, for UIFlow 2.0, for IDE The printing/appearance from batch to batch, but it not affect the use; the actual product may have color difference due to different light or display.
