ST50L integrates ARM Coretex®-M4 (32-bit RISC core operating at a 48MHz frequency) MCU with LoRa modulation.  It offers an ultra-long-range spectrum communication and high interference immunity simultaneously minimizing power consumption.

The ST50L can achieve sensitivity under -136 dBm.  It has high sensitivity and combined with the integrated +21 dBm power amplifier yields.  The industry-leading link makes it optimal for any low data rate application.  LoRa also provides significant advantages in both blocking and selectivity over conventional modulation techniques.  Solving traditional issues between range, interference immunity, and power consumption.
