The S78S is designed & manufactured in a smallest form factor - SiP ( System in Package ). It integrate with Semtech SX1278 and a 32-bit ultra low power Cortex M0L MCU ( STM32L073x ), supporting global 433 MHz or 470 MHz 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.
