Product details

Overview

P-NUCLEO-LRWAN1 from STMicroelectronics is a certified LoRaWAN™ Class A development pack comprising the NUCLEO-L073RZ MCU board and SX1272MB2xAS LoRa®/FSK/OOK extension board, supporting 868 MHz and 915 MHz ISM bands, with -137 dBm sensitivity, +20 dBm RF output, and 157 dB link budget for long-range, low-power IoT node prototyping.

For engineers reviewing the P-NUCLEO-LRWAN1 datasheet, P-NUCLEO-LRWAN1 pinout, P-NUCLEO-LRWAN1 application, or P-NUCLEO-LRWAN1 equivalent, this pack delivers integrated hardware-software validation (I-CUBE-LRWAN), Arduino- and ST morpho-compatible expansion, on-board ST-LINK/V2-1 debugging, and full LoRaWAN™ Class A compliance out-of-box.

Technical Context

The system implements a dual-board architecture: the NUCLEO-L073RZ hosts an ARM® Cortex®-M0+ MCU (192 KB Flash, 20 KB SRAM, 6 KB EEPROM) running I-CUBE-LRWAN firmware, while the SX1272MB2xAS provides LoRa®, FSK/GFSK/MSK/GMSK/OOK modulation, 61 Hz synthesizer resolution, and automatic RF sense with ultra-fast AFC.

Hardware integration uses SPI (NSS/MOSI/MISO/SCK), GPIO pass-through (DIO0–DIO3, RESET), and shared power/ground rails between boards; all RF front-end functions-including +14 dBm high-efficiency PA, 89 dB blocking immunity, and 127 dB+ RSSI dynamic range-are handled exclusively by the SX1272 transceiver.

Key Specifications

Parameter	Value and Actual Design Meaning
RF Frequency Bands	Supports 868 MHz and 915 MHz ISM bands-enables regional LoRaWAN™ deployment without hardware change.
Max Link Budget	157 dB-achieved via -137 dBm sensitivity and +20 dBm output, enabling multi-kilometer outdoor range in sub-GHz bands.
Modulation Support	LoRa®, FSK, GFSK, MSK, GMSK, OOK-allows interoperability with legacy WMBus and IEEE 802.15.4g systems.
MCU Core	ARM® Cortex®-M0+, 32-bit, ultra-low-power-delivers 192 KB Flash/20 KB SRAM/6 KB EEPROM with crystal-less USB and LCD driver.
Debug Interface	On-board ST-LINK/V2-1 with SWD-provides virtual COM port, mass storage, and debug port over single USB Type-B connector.
Expansion Headers	Arduino™ Uno V3 and ST morpho pinouts-grants full access to all STM32L073RZ I/Os including analog, timer, and communication peripherals.

FAQ

Does P-NUCLEO-LRWAN1 support LoRaWAN™ Class C operation?

No. The pack is certified only for LoRaWAN™ Class A operation per I-CUBE-LRWAN v1.2.0 and Semtech SX1272MB2xAS hardware constraints. Class C requires continuous RX listening, which conflicts with the NUCLEO-L073RZ's power architecture and firmware stack configuration.

Can the SX1272MB2xAS board be used independently of the NUCLEO-L073RZ?

Yes-the SX1272MB2xAS is a standalone LoRa®/FSK/OOK transceiver board with standard 0.1" headers. It requires external 3.3 V supply, SPI host controller, and DIO signal routing; no NUCLEO-L073RZ dependency exists for basic RF functionality verification.

What IDEs are officially supported for firmware development?

ST officially supports IAR Embedded Workbench, ARM Keil MDK-ARM, and GCC-based tools including STM32CubeIDE and System Workbench for STM32. All leverage HAL drivers and I-CUBE-LRWAN middleware with full debug visibility via ST-LINK/V2-1.

Is antenna matching required when using the onboard PCB trace antenna?

No-antenna matching components are pre-populated on the SX1272MB2xAS board for 868/915 MHz operation. The PCB trace antenna is tuned and validated per EN 300 220 and FCC Part 15.247 requirements; no user adjustment is needed for regulatory-compliant transmission.
