LoRa/GPS Shield For Arduino 無線射頻擴展板 LoRa Bee 含 GPS 衛星定位模組  RF LoRa 無線射頻擴展板

LoRa / GPS Shield是 LoRa™/ GPS 的擴展板,可以與Arduino一起使用。本產品專為有興趣開發LoRa™/ GPS解決方案的用戶而設計。LoRa / GPS Shield由LoRa / GPS Shield主板和LoRa BEE。在LoRa部分,LoRa / GPS Shield基於SX1276 / SX1278收發器.LoRa / GPS Shield的收發器採用LoRa™遠程調製解調器,可提供超長距離擴頻通信和高抗干擾性,同時最大限度地減小電流消費。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。

在GPS部分,添加L80 GPS(基於MTK MT3339)專為使用通過串口連接到Arduino的應用程序(如定時應用程序或需要GPS信息的一般應用程序)而設計。此GPS模組可以計算並使用存儲在內部閃存中的星曆數據(最多3天)自動預測軌道,即使在低功耗的室內信號電平下,屏蔽​​也能快速固定位置。借助AlwaysLocate™技術,LoRa / GPS防護罩可自適應地調整開/關時間,以根據環境和運動條件實現定位精度和功耗之間的平衡。GPS還支持自動天線切換功能。它可以實現內部貼片天線和外部有源天線之間的切換。而且,

原廠技術文件與教學

The LoRa/GPS Shield is an expension board for LoRa™/GPS for using with the Arduino.This product is intended for those interested in developing LoRa™/GPS solutions.The LoRa/GPS Shield is composed of LoRa/GPS Shield mother board and LoRa BEE.In the LoRa part,the LoRa/GPS Shield is based on the SX1276/SX1278 transceiver.The transceivers of the LoRa/GPS Shield feature the LoRa™ long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption. 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.In th GPS part,the add on L80 GPS (base on MTK MT3339) is designed for applications that use a GPS connected via the serial ports to the arduino such as timing applications or general applications that require GPS information.This GPS module can calculate and predict orbits automatically using the ephemeris data (up to 3 days) stored in internal flash memory, so the shield can fix position quickly even at indoor signal levels with low power consumption.With AlwaysLocate™ technology, the LoRa/GPS Shield can adaptively adjust the on/off time to achieve balance between positioning accuracy and power consumption according to the environmental and motion conditions.The GPS also supports automatic antenna switching function. It can achieve the switching between internal patch antenna and external active antenna.Moreover, it keeps positioning during the switching process.
