The SX1276 transceiver features award-winning LoRa Technology that provided ultra long range spread spectrum communication and high interference immunity while minimizing current consumption.

Using Semtech’s patented LoRa modulation technique SX1276 can achieve a sensitivity of over -148dBm using a low cost crystal and bill of materials. The high sensitivity, combined with the integrated +20dBm power amplifier, yields an industry leading link budget, making it optimal for any application requiring range or robustness. LoRa also provides significant advantages in both blocking and selectivity over conventional modulation techniques, which solves the traditional design compromise between range, interference immunity and energy consumption.
