EK-S78SXB Evaluation Board

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.
