Grove is a very powerful platform developed by Seeed Studio to simplify your IoT projects. We have integrated the grove connector into most boards produced by Seeed for them to 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 featuring the LoRa long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing 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.

Highlighted Features

• The main functional module in Grove - LoRa Radio 433MHz is RFM98,
• The transceiver features the LoRa long range modem
• Provides ultra-long range spread spectrum communication
• 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
  
• We integrated a simple wire antenna to receive the 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 that has an MHF interface to gain more signal.
