Portenta H7 Lite-board

Portenta H7 Lite

The Portenta H7 Lite follows the Arduino MKR form factor, but enhanced with the Portenta family 80 pin high-density connector. Program it with high-level languages and AI while performing low-latency operations on its customizable hardware.


The Portenta H7 Lite is very similar to the Portenta H7, that simultaneously can run high level code along with real time tasks thanks to its two processors. It is, for example, possible to execute Arduino compiled code along with MicroPython one and have both cores to communicate with one another. However, the H7 Lite is a low-cost board with H7 functionalities that can be configured to specific use cases.

Nano Form Factor
Portenta H7 Microcontroller

The Portenta H7 allows for programming with high-level languages and AI while performing low-latency operations on its customizable hardware.

STM32H747XI dual Cortex®-M7+M4 32bit low power Arm® MCU

H7's main processor is the dual core STM32H747 including a Cortex® M7 running at 480 MHz and a Cortex® M4 running at 240 MHz. The two cores communicate via a Remote Procedure Call mechanism that allows calling functions on the other processor seamlessly.
