NUCLEO-L552ZE-Q

The "STM32 Nucleo-144" board is a development platform that provides users with a cost-effective and flexible way to experiment with various performance and power consumption features offered by STM32 microcontrollers. It is designed for prototyping and creating new concepts.

Key features and specifications of the "STM32 Nucleo-144" development board include:

• STM32L552ZET6QU microcontroller: The board is built around the STM32L552ZET6QU microcontroller, which comes in an LQFP144 package. This microcontroller is part of the STM32L5 series and offers a combination of performance, low power consumption, and advanced features.

• Compatibility: The board supports ARDUINO Uno V3 connectors, ST morpho headers, and ST Zio connectors, providing a wide range of options for extending the board's functionality, including the use of custom shields.

• Onboard ST-LINK debugger/programmer: The integrated ST-LINK debugger and programmer eliminate the need for an external probe, simplifying programming and debugging tasks.

• User LEDs and buttons: The board includes three user LEDs and two buttons (one for user interaction and one for resetting the board).

• Comprehensive software support: Users can take advantage of the STM32Cube MCU package, which offers a wealth of free software libraries and examples to streamline software development for STM32 microcontrollers.

• Power supply options: The board can be powered through ST-LINK, USB VBUS, or external power sources, providing flexibility in different use cases.

• USB Type-C connector: The board features a USB Type-C connector, supporting USB Full-Speed (FS) for device connectivity.

• Internal SMPS: The board is equipped with an internal Switched-Mode Power Supply (SMPS) to generate the Vcore logic supply, which can be essential for managing power consumption.

• 768 kHz crystal oscillator: The onboard crystal oscillator provides accurate timing for various operations.

• Support for multiple IDEs: The board is compatible with a range of Integrated Development Environments (IDEs), including IAR Embedded Workbench, Keil MDK, and GCC-based IDEs.
