描述
Grove – LoRa Radio 868MHz 遠距離無線射頻通訊模組 Seeed 原裝進口
Grove是由Seeed Studio開發的一個非常強大的平台，可以簡化您的物聯網項目。我們已經將grove連接器集成到Seeed生產的大多數主板上，以使它們成為一個系統。這一次，我們將Grove與LoRa相結合，為您提供超遠距離無線模塊。Grove – LoRa Radio 868MHz的主要功能模塊是RFM95，它是一款採用LoRa遠程調製解調器的收發器，提供超長距離擴頻通信和高抗干擾能力，同時微型電流消耗小。Grove的核心 – LoRa Radio 868MHz是ATmega168，這是一種廣泛使用的芯片，具有很高的性能和低功耗，特別適用於這個Grove模塊。
我們已經集成了一個簡單的線天線接收信號，如果信號太弱，不用擔心，天線旁邊的MHF連接器用於增加一個具有MHF接口的第二個天線來獲得更多的信號。
這是868MHz版本，可以用於868MHz通信。您還可以在Grove – LoRa Radio 433MHz上找到433MHz的版本。
注意：
- 請保持天線垂直於電路板，並儘可能筆直以達到最佳性能。
- 請避免在天線附近製造大的金屬物體，如果您需要為您的設備添加海角，也不建議使用金屬海角。

數據表
Grove is a very powerful platform developed by Seeed Studio to simplify your IoT projects.We have integrated the grove connector to most boards produced by Seeed to make them become a system. This time, we combined Grove with LoRa to provide an ultra-long-range wireless module for you.The main functional module in Grove – LoRa Radio 868MHz is RFM95, which is a transceiver features the LoRa long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst mini-missing current consumption. The heart of Grove – LoRa Radio 868MHz is ATmega168, a widely used chip with very high-performance and low power consumption, especially suitable for this grove module.There we already integrated a simple wire antenna to receive signal, if the signal is too weak to receive, don’t worry, the MHF connector next to the antenna is for adding a second antenna which has MHF interface to gain more signal.This is the 868MHz version, which can be used for 868MHz communication. You can also find the version for 433MHz at Grove – LoRa Radio 433MHz.Note:
- Please keep the antenna vertical to the board and as straight as possible to make the best performance.
- Please avoid making any big metal object near the antenna and a metal cape is also not recommended if you need to add a cape for your device.
