商品說明

Grove LoRa Radio 868MHz 無線射頻開發模組

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RFM98，它是一款採用LoRa遠程調製解調器的收發器，可提供超長距離擴頻通信且高抗干擾性，同時消耗微量電流.Grove-LoRa Radio 868MHz的核心處理器是ATmega168的，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來接收信號，如果信號太弱，不用擔心，天線旁邊的MHF連接器可以用來增加一個帶有MHF接口的天線，雙天線可以獲得更多的信號。

Grove LoRa Radio 868MHz

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.

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.
