STM32 Nucleo expansion boards carry all the required components to
  • Evaluate ST devices to be used together with an STM32 MCU
  • Build STM32-based applications leveraging functionality and performance of ST’s device portfolio

The expansion boards are equipped with standardized interconnections, such as

  • an Arduino Uno R3 connector, or
  • a Morpho connector for a higher level of connectivity
Each expansion board is supported by STM32-based software modules.

The combination of STM32 Nucleo boards and expansion boards is a unified scalable approach with unlimited possibilities for application development, prototyping or product evaluation.

Certified LoRaWAN™ implementation for evaluation and development purposes

Created to help explore and develop LoRaWAN solutions, the P-NUCLEO-LRWAN1 development tool forms a convenient HW bundle with the NUCLEO-L073RZ board based on the STM32L0 ARM® Cortex®-M0+ ultra-low-power microcontroller and  dedicated expansion board implementing a SX1272 radio supporting LoRaTM technology and a high-performance FSK/OOK RF transceiver modem. The HW bundle operates in the 868 to 915MHz ISM band range.

  • Ultra-low-power STM32L0 Series MCU, Cortex -M0+ based with 192 Kbytes of Flash memory, 20 Kbytes of RAM, 6 Kbytes of EEPROM, LCD, crystal-less USB, T-RNG, PCROP
  • 157 dB maximum link budget
  • +20 dBm, 100 mW constant RF output versus Vsupply
  • +14 dBm high efficiency PA
  • Bidirectional end-devices with class A and class C protocol support
  • EU 868 MHz ISM band ETSI (European telecommunications standards institute) compliant
  • US 915 MHz ISM band FCC (federal communications commission) compliant
  • LoRaWAN™ test application for certification tests included

Used together with the certified software solution I-CUBE-LRWAN and the LoRaWAN compliant Class A stack based on STM32Cube, the HW bundle makes an excellent development tool to enable developers to practice and build LoRaWAN solutions.​
