Portenta H7 Lite is a high-performance MCU development board and an entry-level product in the Arduino Portenta H7 series. It uses the same STM32H7 MCU chip as the Arduino Portenta H7 but comes with less peripherals to offer a powerful development board at a more affordable price.

The board features a Cortex-M7 core with a clock frequency of up to 480 MHz and a Cortex-M4 core, enabling complex multi-threaded processing and high-speed data handling. It also has 16MB of QSPI Flash memory and 8MB of SDRAM, providing sufficient storage and computing power for most applications.

Despite having fewer peripherals, Portenta H7 Lite still has rich communication interfaces, including USB, Ethernet, and the CAN bus. Moreover, it can be combined with various Arduino MKR expansion boards by its MKR shape to easily and flexibly extend sensors, actuators, and communication interfaces.

Portenta H7 Lite supports multiple operating systems, such as FreeRTOS, Mbed OS, and Zephyr, as well as various development toolchains and libraries, such as Arduino IDE, STM32CubeIDE, and Mbed Studio, providing users with a flexible and diverse development environment.

In summary, Portenta H7 Lite is a powerful and cost-effective development board, suitable for beginners and intermediate developers in various IoT, robotics, and AI application scenarios.

The Perfect Fit with the Portenta H7 Lite

What is the difference between Portenta H7, Lite and Lite Connected?

The Portenta H7 is specially designed for high performance in industrial environments. While the hardware is highly customizable, Arduino provide three ready-made solutions:

Portenta H7: The full version. Program using high-level languages and AI while performing low-latency operations on its customizable hardware.

Portenta H7 Lite: A cost-optimized solution, ideal for complex environments where radio communication is not suitable or possible. Designed for developers who want to leverage the same computational power of the Portenta H7, but do not need wireless connectivity, high-resolution video interface, and additional security features.

Portenta H7 Lite Connected: Fills the gap between the full and Lite variants by integrating wireless connectivity, hitting another sweet spot for industrial-strength solutions.
