Product details
Overview
P-NUCLEO-LRWAN2 from STMicroelectronics is a LoRa® HF band (868/915/923 MHz) starter pack comprising two Nucleo development boards (NUCLEO-L073RZ and NUCLEO-F746ZG), one USI® I-NUCLEO-LRWAN1 sensor node expansion board, and one RisingHF LRWAN_GS_HF1 gateway expansion board - enabling end-to-end LPWAN prototyping with integrated sensors (HTS221, LPS22HB, LSM303AGR) and dual-core MCU control (STM32L073RZT6 + STM32F746ZGT6).
For engineers reviewing the P-NUCLEO-LRWAN2 datasheet, P-NUCLEO-LRWAN2 pinout, P-NUCLEO-LRWAN2 application, or P-NUCLEO-LRWAN2 equivalent, this kit delivers validated LoRaWAN® Class A/C packet forwarding, AT-command-accessible sensor-node firmware, IEEE-802.3-compliant Ethernet on the gateway, and preloaded I-CUBE-LRWAN demonstration software - supporting rapid evaluation of sensor-to-cloud LPWAN architecture in industrial monitoring, smart agriculture, and asset tracking.
Technical Context
The kit implements a split-architecture LPWAN system: the NUCLEO-L073RZ (STM32L073RZT6, 32 MHz, 192 KB Flash) hosts the sensor node firmware and communicates via UART to the USI® WM-SG-SM-42 LoRa® module (SX1272 transceiver, SF7–SF12 adaptive), while the NUCLEO-F746ZG (STM32F746ZGT6, 216 MHz, 1 MB Flash) runs the Semtech packet forwarder and interfaces with the RisingHF LRWAN_GS_HF1 (SX1301/SX1257 baseband) over SPI and GPIO.
Both boards integrate ST-LINK/V2-1 debuggers with USB re-enumeration (mass storage, VCP, SWD), ARDUINO® Uno V3-compatible headers (Zio on F746ZG, standard on L073RZ), and ST morpho headers for full I/O access - enabling hardware-level customization of RF timing, sensor sampling, and network stack behavior without external tooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-node MCU | STM32L073RZT6: Arm Cortex-M0+, 32 MHz, 192 KB Flash, 20 KB SRAM - enables ultra-low-power sensor polling and LoRa® AT command handling. |

| LoRa® Transceiver (Node) | Semtech SX1272: 868/915/923 MHz, -137 dBm sensitivity, SF7–SF12, 125 kHz bandwidth - provides long-range, low-data-rate sensor telemetry with adaptive link budget. |
| LoRa® Baseband (Gateway) | SX1301 + SX1257: 8-channel concurrent demodulation, -140 dBm sensitivity at 300 bit/s, 6 dBm output - enables scalable gateway deployment with Class A/C uplink/downlink support. |
| Integrated Sensors | HTS221 (±0.5°C temp, ±3.5% RH), LPS22HB (±0.01 hPa pressure), LSM303AGR (±2/±4/±8 g accel, ±245/±500/±2000 dps gyro) - delivers calibrated environmental and motion data without external signal conditioning. |
| Connectivity | Ethernet (IEEE-802.3-2002), USB OTG (F746ZG), Mini-AB USB (L073RZ), ARDUINO® Uno V3 & ST morpho headers - allows direct connection to LAN infrastructure and flexible peripheral expansion. |
Availability

Manufacturer
STMicroelectronics is a global semiconductor leader headquartered in Geneva, Switzerland, designing and manufacturing microcontrollers, analog ICs, MEMS sensors, and power management solutions for industrial, automotive, and IoT applications.
The STM32 Nucleo series - including P-NUCLEO-LRWAN2 - is engineered to accelerate prototyping of wireless connectivity stacks by integrating certified modules, standardized expansion interfaces, and vendor-validated middleware (e.g., I-CUBE-LRWAN) into plug-and-play development kits.
FAQ
Does P-NUCLEO-LRWAN2 include pre-flashed firmware?
Yes. The NUCLEO-L073RZ and NUCLEO-F746ZG boards ship with demonstration firmware preloaded from the I-CUBE-LRWAN STM32Cube Expansion Package. This includes sensor data acquisition, LoRa® AT command execution, packet forwarding logic, and Ethernet-based network server communication - ready to run without initial compilation or flashing.
Can the I-NUCLEO-LRWAN1 sensor board operate independently of the NUCLEO-L073RZ?
No. The I-NUCLEO-LRWAN1 lacks its own debugger or standalone power management circuitry. It requires the NUCLEO-L073RZ as host controller for UART-based AT command interface, sensor initialization, and power regulation - though its ARDUINO®-compatible pinout allows mechanical mounting on other compatible carriers with appropriate level-shifting and firmware adaptation.
What LoRaWAN® network servers are supported out-of-the-box?
The LRWAN_GS_HF1 gateway board supports Semtech's standard packet forwarder protocol and is preconfigured for compatibility with public and private LoRaWAN® network servers including The Things Network (TTN), Actility ThingPark, and ChirpStack. DNS and NTP support enables automatic time synchronization and server discovery without manual IP configuration.
Is antenna calibration required before using P-NUCLEO-LRWAN2?
No. The kit ships with factory-assembled and locked antennas compliant with FCC/ETSI RF exposure limits for 868/915/923 MHz bands. Antenna matching networks are pre-tuned on both the I-NUCLEO-LRWAN1 (PCB trace antenna) and LRWAN_GS_HF1 (SMA-connected dipole), eliminating need for user calibration or RF tuning tools during initial evaluation.
