Description
433 MHz RFM95 radio module of the long range (Long Range: LoRa). It allows for data transmission at the distance of up to 500 m using a piece of wire as an antenna. The system provides noise resistance and a small current consumption. It also has a u.FL connector for additional antenna. The set includes a cable adapted to SeeedstudioBase Shield v2.0.
Module has 4-pin cable for Base Shield v2.0.
The heart of the module is the ATmega168 microcontroller - system with high efficiency and low energy consumption. LoRa radio has mounted a piece of wire as an antenna. However, if the signal is too weak, you can connect the second antenna to the u.FL connector.
