Arduino Portenta H7 Lite Connected Removes the Costly High-Res Video Interface

Written by Stephen Vicinanza

Arduino Portenta H7 Lite Connected removes the costly high-res video interface. The Portenta H7 Lite Connected is meant to provide the computational AI application power of the Portenta H7. It keeps the low latency with a module that is more cost-effective due to removing the high-resolution video interface feature.

The H7 Lite Connect bridges the gap between the H7 and the H7 Lite. The connectivity is wirelessly integrated which adds another layer to Arduino Pro users, who are looking to build that perfect solution. It marries together a combination of ease, simplicity, and performance.

The H7 Lite Connected can run high-level code and real-time tasks simultaneously from two processors. Arduino uses the example of executing at the same time Arduino-compiled and MicroPython code. And have two cores communicate through a Remote Procedure Call mechanism, which allows calling functions on the other processor for real-time, seamless multitasking.

The ability to run two systems at once can run low-latency sensor/actuator interaction while running machine learning algorithms.

The Portenta H7 Lite Connected

Benefits include:

  • Simultaneously manage Wi-Fi and Bluetooth wireless connectivity
  • Micropython and high-level programming language support
  • Onboard secure element security, for secure certificate storage and management
  • Dual Core
  • AI at the edge – it can run AI state machines

The Portenta H7 Lite Connected main processor is an STM32H747 which includes a Cortex-M7 that runs at 480MHz and a Cortex-M4 that runs at 244MHz. There is communication between the two processors using a Remote Procedure Call mechanism, which allows call functions from one processor to the other, in a seamless system.

Both processors have in-chip peripherals and can run software that includes –

  • Native Mbed applications
  • MicroPython and JavaScript (via an interpreter)
  • Arduino sketches on top of the Arm MBed OS
  • TensorFlow Lite

The module’s programming connector is a USB-C port that is also used for power and can deliver power to OTG-connected devices or as a USB Hub.

The module can be used to access Arduino IoT Cloud, which can simplify and quickly ensure secure communication across all IoT devices.

This module adds two 80-pin high-density connectors on the bottom of the unit. This widens scalability and offers a range of applications.

The Arduino Cloud has a free trial version.
