Detailed Review:

The Arduino Portenta H7 boasts impressive features, including two independent cores that enable parallel execution of tasks. This unique capability allows developers to combine Arduino-compiled code with MicroPython or other languages, expanding its potential use cases. Additionally, the onboard support for peripherals like Wi-Fi, Bluetooth, keyboard, mouse, external monitor, and sound makes the H7 a versatile single-board computer.

However, setting up the development environment for the H7 can be a bit cumbersome, especially given its recent release. While the official Arduino IDE provides support, there is also an alpha version of the new Arduino Pro IDE, which offers a more streamlined development experience. It allows users to select the target board through a pop-up menu, simplifying the process.

Despite its potential, the Portenta H7 faces challenges due to the current lack of fully developed tools, limited example code, and sparse community support. This may make it less accessible to beginners or hobbyists, as the board requires a higher level of expertise to utilize its full capabilities. Additionally, interfacing with advanced features may require the use of a breakout board, which could be complex to implement due to high-density connectors.


The Arduino Portenta H7 Development Board is a powerful and versatile embedded computing platform that appeals to experienced developers seeking advanced capabilities. While its potential for various applications is evident, it currently faces some limitations in terms of the developing ecosystem. As the tools, example code, documentation, and community support continue to evolve and mature, the H7 holds the promise of becoming a leading system-on-module in the future. For now, it remains a top choice for professionals looking to build sophisticated embedded applications. The board’s compatibility with the Arduino IoT Cloud simplifies secure communication for all connected things, making it a valuable tool for creating innovative smart projects.
