Description
The B-L072Z-LRWAN1 LoRa
®
Discovery kit is a development tool to learn and develop
solutions based on LoRa
®
and FSK/OOK technologies. This Discovery kit features an all-in-
one open module CMWX1ZZABZ-091 (by Murata). The module is powered by an
STM32L072CZ and an 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,
user has access to all STM32L072 peripherals such as ADC, 16-bit timer, LP-UART, I
2
C,
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. It is available inside the
I-CUBE-LRWAN firmware package. Several examples, as an AT-command stack, are
available to help users setting up a complete LoRaWAN
™
node.
