Grove - LoRa Radio 868MHz

The Grove - LoRa Radio 868MHz module has a RFM95 module, 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 the Grove - LoRa Radio 868MHz is an ATmega168, a widely used chip with very high-performance and low power consumption, especially suitable for this grove module. 

A simple wire antenna is wired on-board 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 to gain more signal. 

This is the 868MHz version, which can be used for 868MHz communication. We also have a 433MHz here.

Note

• Please keep the antenna vertical to the board and as straight as possible to get 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.
