The S76S is designed & manufactured in a smallest form factor - SiP ( System in Package ). It integrate with Semtech SX1276 and a 32-bit ultra low power Cortex M0L MCU ( STM32L073x ), supporting global 863MHz ~ 928MHz ISM-Bands.
Capable of 2-way communication and reach over 16 km ( 10 miles ) distance in our field test.
This product is designed with multiple easy to use interface ( I2C/SPI/UART/GPIO ), fine-tuned RF performance and will be offered with complete SDK library & ready to go HDK, it can significantly help the users to shrink the size of end device and simplify the development efforts for any LoRa applications.

The S76S integrates ARM Coretex®-M0+ (32-bit RISC core operating at a 32MHz frequency) MCU and LoRa/FSK modulation that provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.The S76S is the first SiP module of LoRa in the world as well.
The 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 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.
