Grove is a very powerful platform developed by Seeed Studio to simplify your IoT projects. Seeed has integrated the grove connector to most boards produced to make them become a system. This time, Seeed 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 minimizing 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.
Seeed already integrated a simple wire antenna to receive signal, if the signal is too weak to receive, don’t worry, the MHF/U.FL connector next to the antenna is for adding a second antenna which has MHF/U.FL interface to gain more signal.
Note: This is the 868MHz version, which can be used for 868MHz communication.
