Dragino LoRa Shield – LoRA 無線通訊擴展板 433MHZ

Dragino LoRa Shield是Arduino 擴展板型式的長距離收發器,基於開源庫.LoRa Shield 允許用戶發送數據並在低數據速率下達到極長的距離。它提供超長距離擴展頻譜通信和高抗干擾性,同時最小化電流消耗。基於RFM98W的LoRa Shield專門針對灌溉系統,智能計量,智能城市,智能手機檢測,樓宇自動化等專業無線傳感器網絡應用。

使用Hope RF的專利LoRa™調製技術,LoRa Shield可以使用低成本晶體和物料清單,實現超過-148dBm的靈敏度。高靈敏度與集成的+ 20 dBm功率放大器相結合,產生業界領先的鏈路預算,使其適用於任何需要範圍或穩健性的應用。與常規調製技術相比,LoRa™在阻斷和選擇性方面也提供了顯著的優勢,解決了傳統設計在範圍,抗干擾性和能耗之間的妥協。

這些器件還支持包括WMBus,IEEE802.15.4g在內的高性能(G)FSK模式。LoRa Shield提供卓越的相位噪聲,選擇性,接收器線性度和IIP3,比競爭器件的電流消耗顯著降低。

Dragino LoRa Shield – support 433M frequency

The Dragino LoRa Shield is a long range transceiver on a Arduino shield form factor and based on Open source library.The LoRa Shield allows the user to send data and reach extremely long ranges at low data-rates.It provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption.The LoRa Shield based on RFM98W targets professional wireless sensor network applications such as irrigation systems, smart metering, smart cities, smartphone detection, building automation, and so on.Using Hope RF’s patented LoRa™ modulation technique the LoRa Shield can achieve a sensitivity of over -148dBm using a low cost crystal and bill of materials. The high sensitivity combined with the integrated +20 dBm power amplifier yields industry leading link budget making it optimal for any application requiring range or robustness. LoRa™ also provides significant advantages in both blocking and selectivity over conventional modulation techniques, solving the traditional design compromise between range, interference immunity and energy consumption.These devices also support high performance (G)FSK modes for systems including WMBus, IEEE802.15.4g. The LoRa Shield deliver exceptional phase noise, selectivity, receiver linearity and IIP3 for significantly lower current consumption than competing devices.
