  • The B-L072Z-LRWAN1 LoRa®/Sigfox™ Discovery kit is a development tool to learn and develop solutions based on LoRa®, Sigfox™, and FSK/OOK technologies. This Discovery kit features the all-in-one CMWX1ZZABZ-091 open module by Murata. The module is powered by an STM32L072CZ microcontroller and SX1276 transceiver. The transceiver features the LoRa® long-range modem, providing ultra-long-range spread-spectrum communication and high interference immunity, minimizing current consumption. Since CMWX1ZZABZ-091 is an open module, the user has access to all STM32L072CZ peripherals such as ADC, 16-bit timer, LP-UART, I2C, SPI, and USB 2.0 FS (supporting BCD and LPM).

    The B-L072Z-LRWAN1 Discovery kit includes an ST-LINK/V2-1 embedded debug tool interface, LEDs, push-buttons, antenna, Arduino™ Uno V3 connectors and USB OTG connector in Micro-B format.
    The LoRaWAN™ stack supports Class A, Class B, and Class C. It is available in the I-CUBE-LRWAN firmware package. Several examples, including an AT-command stack, are available to help users set up a complete LoRaWAN™ node.
    The Sigfox™ stack is RC1, RC2, RC3c, and RC4 compliant. It is available in the X-CUBE-SFOX Expansion Package. Several examples, including an AT-command modem, are also available to help users set up a complete Sigfox™ node.
