STM32 Nucleo-144 development board with STM32L496ZGTP MCU, SMPS, supports Arduino, ST Zio and morpho connectivity

The STM32 Nucleo-144 boards (NUCLEO-L496ZG and NUCLEO-L496ZG-P) provide an affordable and flexible way for users to try out new concepts and build prototypes using the various combinations of performance, power consumption and features provided by the STM32 microcontroller.

The ST Zio connector, which extends the Arduino Uno V3 connectivity, and the ST morpho headers provide an easy means of expanding the functionality of the Nucleo open development platform with a wide choice of specialized shields. The STM32 Nucleo-144 board does not require any separate probe as it integrates the ST-LINK/V2-1 debugger/programmer. The STM32 Nucleo-144 board comes with the STM32 comprehensive software HAL and LL libraries, and various packaged software examples.

Key Features

  • STM32 microcontroller in LQFP144 package
  • SMPS: significantly reduces power consumption in Run mode, by generating Vcore logic supply from an external DC/DC converter. This function is only available on ‘-P’ suffixed boards
  • 3 user LEDs
  • 2 push-buttons: USER and RESET
  • LSE crystal:
    • 32.768 kHz crystal oscillator
  • 2 types of extension resources:
    • ST Zio connector including: support for Arduino™ Uno V3 connectivity (A0 to A5, D0 to D15) and additional signals exposing a wide range of peripherals
    • ST morpho extension pin header footprints for full access to all STM32 I/Os
  • USB OTG or full-speed device with Micro-AB connector
  • 4 source options for power supply:
    • E5V from ST morpho connectors
    • ST-LINK/V2-1 USB connector
    • USB charger
    • VIN (7 - 12 V) from ST Zio connector
  • On-board ST-LINK/V2-1 debugger/programmer with SWD connector:
    • ST-LINK/V2-1 standalone kit capability
    • USB re-enumeration capability: virtual COM port, mass storage, debug port
  • Comprehensive free software HAL and LL libraries including a variety of software examples
  • Support of a wide choice of Integrated Development Environments (IDEs) including IAR , Keil® , GCC-based IDEs
