1. General Description
The S76S integrates ARM Coretex®-M0+ (32-bit RISC core operating at a 32MHz frequency) MCU with LoRa
TM
modulation that provides ultra-long range spread spectrum communication and high interference immunity
whilst minimizing current consumption.
S76S can achieve a sensitivity of over -137 dBm. The high sensitivity combined with the integrated +20 dBm
power amplifier yields industry leading link budget making it optimal for any low data rate application requiring
range or robustness. LoRa
TM
also provides significant advantages in both blocking and selectivity over
conventional modulation techniques, solving the traditional design compromise between range, interference
immunity and energy consumption.
