Introducing the LoRa^® Discovery Kit from STMicroelectronics enabling quick development of IoT applications

STMicroelectronics have launched the B-L072Z-LRWAN1 LoRa^® Discovery kit, this development tool is designed to help engineers learn about and develop solutions based on LoRa^® and FSK/OOK technologies.

The Discovery kit features an all-in-one open LoRa module CMWX1ZZABZ by Murata. The Murata module is powered by STMicroelectronics STM32L072CZ MCU and the SX1276 transceiver from SEMTECH. Furthermore the on-board STM32L072CZ MCU is open allowing use of all the STM32 tools with the module. The transceiver features the LoRa^® long-range modem, providing ultra-long-range spread spectrum communication and high interference immunity, minimizing current consumption. The CMWX1ZZABZ from Murata is an open module giving the user access to all STM32L072 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 is certified class A and C compliant and is available in the I-CUBE-LRWAN firmware package. Several examples, as an AT-command stack, are also available to help users setting up a complete LoRaWAN™ node.
