Grove - LoRa Radio module 868MHz

868MHz RFM95long-range radio module (Long Range: LoRa). Enables data transmission atdistances up to approx. 800 m,using the cable as an antenna. The module is equipped with au.FL connectorso it is possible to connect an additional antenna. The set includes a cable with Grove connector adapted to SeeedstudioBase Shield v2.0.The system operates with voltage of 3.3 V and 5 V.

The module comes with 4-pin cable for Base Shieldv2.0.

The module is equipped with an ATmega 168 microcontroller, a commonly used high-performance, low power consumption chip and RFM95 chip based on SX1276 LoRa®which is a transceiver (transmitter-receiver) providing communication in the spread spectrum with a very long range and high resistance with minimal power consumption. We also offer a 433MHzradio module.
