Application
The NUCLEO-U545RE-Q is an STM32 Nucleo-64 development board designed for evaluating and prototyping applications based on the STM32U545RET6Q ultra-low-power Arm Cortex-M33 microcontroller. It integrates an on-board ST-LINK/V3E debugger/programmer supporting Virtual COM Port, Mass Storage, and drag-and-drop programming, eliminating the need for an external debug probe. The board includes an on-board SMPS to reduce power consumption during Run mode and supports Arduino™ Uno V3 and ST morpho expansion connectors for easy hardware expansion. With TrustZone® security, a 160 MHz Cortex-M33 core, and full compatibility with the STM32Cube software ecosystem, including STM32CubeIDE, STM32CubeMX, and STM32CubeU5, the NUCLEO-U545RE-Q is ideal for secure IoT devices, industrial automation, smart metering, healthcare equipment, wearable electronics, battery-powered embedded systems, and rapid development of low-power secure applications. It is an **Active** product in the STM32 Nucleo development platform.
