Provides ultra-long range spread spectrum communication
Is ATmega168
The 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.
A simple wire antenna to receive signal has already been integrated, 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. This is the 868 MHz version, which can be used for 868 MHz communication.
