STM32 Nucleo-H755ZI Development Board - ARM Cortex-M7/M4 MCU With ST-LINK Debugger

About This Product

For the electronics tinkerers and embedded developers out there, this STM32 Nucleo-H755ZI board is a seriously powerful development platform. It features the STM32H755ZI microcontroller with both ARM Cortex-M7 and Cortex-M4 cores running side by side - that's some serious processing power for embedded applications. The board follows the Nucleo-144 form factor, meaning it's packed with connectivity options including the ST Zio connector (which extends Arduino Uno V3 compatibility) and ST morpho headers for expanding functionality with various shields. You get three user LEDs, two push-buttons (one user, one reset), and a 32.768 kHz crystal oscillator onboard. The flexible power supply options are nice - you can run it from the ST-LINK, USB VBUS, or external sources. Speaking of ST-LINK, it's built right into the board so you don't need a separate debugger/programmer - it shows up as mass storage, virtual COM port, and debug port when you connect via USB. There's even an external or internal SMPS to generate Vcore logic supply for better power efficiency. You get Ethernet compliant with IEEE-802.3-2002, USB OTG full speed, and all the support you need with free software libraries through STM32Cube MCU Package. It works with all the major IDEs too - IAR Embedded Workbench, MDK-ARM, and STM32CubeIDE. Whether you're prototyping a new product, learning embedded systems, or working on a complex IoT project, this board gives you enterprise-level features at a hobbyist-friendly price point. The documentation and community support for STM32 are excellent too, so you won't be left figuring things out on your own.
