Description
The Lora Shield is a long range transceiver in an Arduino shield format. The shield allows data to bent and received at low data rates, utilizing spread spectrum communication with high interference immunity and low current consumption.
The shield is based on Semtech's SX1276/SX1278 chips. The shield uses Hope RF's patented LoRaTM modulation techniques which can achieve a sensitivity of over -148dBm. LoRaTM provides significant advantages in both blocking and selectivity compared to traditional modulation techniques.
