Product details
Overview
P-NUCLEO-LRWAN3 from STMicroelectronics is a LoRa® LF-band (433/470 MHz) starter pack comprising two Nucleo development boards (NUCLEO-L073RZ and NUCLEO-F746ZG), one RisingHF LRWAN_NS1 sensor node board, and one RisingHF LRWAN_GS_LF1 gateway board - enabling full end-to-end LPWAN prototyping with integrated STM32L073RZT6 (32 MHz, 192 KB Flash) and STM32F746ZGT6 (216 MHz, 1 MB Flash) MCUs, HTS221/LPS22HB/LSM6DS3/LIS3MDL sensors, and Semtech SX1278/SX1301 transceivers.
For engineers reviewing the P-NUCLEO-LRWAN3 datasheet, P-NUCLEO-LRWAN3 pinout, P-NUCLEO-LRWAN3 application, or P-NUCLEO-LRWAN3 equivalent, this kit supports rapid evaluation of LoRaWAN® Class A/C network architecture, sensor-to-gateway data flow, AT-command-driven node configuration, and interoperability with public/private LoRaWAN® network servers including The Things Network and Actility.
Technical Context
The kit implements a dual-board LoRaWAN® system: the NUCLEO-L073RZ hosts the LRWAN_NS1 sensor node using an STM32L071 MCU and SX1278 transceiver for ultra-low-power transmission (–137 dBm sensitivity, 14–20 dBm output); the NUCLEO-F746ZG controls the LRWAN_GS_LF1 gateway via SX1301/SX1255 baseband ICs supporting 8-channel SF7–SF12 adaptive demodulation (–140 dBm sensitivity at 300 bit/s) and Class A/C protocol compliance.
Both boards integrate ST-LINK/V2-1 debuggers with USB mass storage, Virtual COM port, and SWD interfaces; the sensor node includes HTS221 (±0.5 °C temp accuracy), LPS22HB (±0.01 hPa pressure), LSM6DS3 (±2 g/±250 dps IMU), and LIS3MDL (±1.5 µT magnetometer), all accessible via Arduino-compatible headers and ST Morpho expansion pins.

Manufacturer
STMicroelectronics is a global semiconductor leader headquartered in Geneva, Switzerland, designing and manufacturing microcontrollers, sensors, power ICs, and analog/mixed-signal products for industrial, automotive, and consumer applications.
The P-NUCLEO-LRWAN3 belongs to ST's STM32 Nucleo ecosystem - engineered to accelerate LoRaWAN® adoption by providing validated hardware stacks, preloaded firmware (I-CUBE-LRWAN), and cross-platform toolchain support (Keil, IAR, GCC) for low-power wide-area network development.
FAQ
Does P-NUCLEO-LRWAN3 support LoRaWAN® Class B operation?
No. The LRWAN_GS_LF1 gateway board implements only LoRaWAN® Class A and Class C functionality per its SX1301 firmware and packet forwarder configuration. Class B requires precise time-synchronized beacons and GPS timing, which are not included in this reference design or supported by the preloaded I-CUBE-LRWAN software stack.
Can the LRWAN_NS1 sensor node operate independently without the NUCLEO-L073RZ board?
No. The LRWAN_NS1 is an Arduino-compatible expansion board that lacks onboard programming/debug circuitry and relies entirely on the NUCLEO-L073RZ's ST-LINK/V2-1 interface for firmware upload, serial AT command control, and power delivery - it has no standalone USB or bootloader capability.
What is the maximum usable range between LRWAN_NS1 and LRWAN_GS_LF1 in open-field conditions?
Under ideal line-of-sight conditions with omnidirectional antennas and 20 dBm node output, measured range exceeds 5 km. Real-world indoor or urban deployments typically achieve 300–1200 m depending on antenna placement, building materials, and local RF noise - consistent with SX1278's –137 dBm sensitivity and SF12 spreading factor performance.
Is the I-CUBE-LRWAN software package compatible with STM32CubeIDE?
Yes. Starting with I-CUBE-LRWAN v3.0.0, ST provides native project templates and middleware integration for STM32CubeIDE (v1.7.0+). The package includes HAL drivers, LoRaWAN® stack (v4.4.3), AT command parser, and sensor abstraction layers fully aligned with STM32CubeMX configuration and code generation workflows.
