SX1276 + STM32L073x Module AcSiP S76S

  • SX1276 + STM32L073x Module AcSiP S76S
SX1276 + STM32L073x Module AcSiP S76S

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.
