The P-NUCLEO-LRWAN1 from STMicroelectronics is an STM32 Nucleo pack for 32-bit STM microcontrollers demonstrating the capabilities of the LoRa® low-power wireless wide-area networking technology.

The pack includes an STM32 NUCLEO-L073RZ board. This board features a low-power, 32-bit STM32L0 MCU based on the ARM® Cortex®-M0 processor core. Supplied with the controller board is the SX1272MB2xAS LoRa extension board from Semtech.

The development kit is also backed by a certified embedded software solution from ST, the I-CUBE-LRWAN. The combination of this software and the two boards provides the means to implement a complete LoRaWANTM Class A node.

As well as supporting the LoRa RF modulation scheme and the LoRaWAN networking protocol, the P-NUCLEO-LRWAN1 also enables designers to implement the frequency-shift keying and on-off keying methods of RF signal modulation.

The pack is ideal for designers developing systems to operate in either the 868MHz or 915MHz ISM frequency bands.
