Grove LoRa Radio 433MHz 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。

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 433MHz

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 433MHz is RFM98, 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 433MHz 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.

Features

  • Using RFM95 module based on SX1276 LoRa®
  • ~28mA(Avg) @+20dBm continuous transmit
  • ~8.4mA(Avg)@standby mode
  • ~20mA(Avg) @receive mode, BW-500kHz
  • Simple wire antenna or MHF Connector for external high gain antenna
  • +20dBm – 100 mW Power Output Capability
