Description
The STM32 Nucleo pack for LoRa
®
technology
and high-performance FSK/OOK RF transceiver
modem (P-NUCLEO-LRWAN1) is a development
tool to learn and develop solutions based on
LoRa
®
and FSK/OOK technologies.
This tool, in association with the certified
em
bedded software solution (I-CUBE-LRWAN),
provides the means to set up a complete
LoRaWAN
node compliant with class A, based
on the Semtech SX1272MB2xAS LoRa
®
extension board. To control the LoRa
®
extension
board, the pack comes with a NUCLEO-L073RZ
board based on the ultra-low-power, 32-bit
STM32L0 based on ARM
®
Cortex
®
-M0
microcontroller. The I-CUBE-LRWAN is
LoRaWAN
class A certified.
This pack is the perfect fit for any countries with
868 MHz
or 915 ISM frequency bands.
