Overview

The Portenta H7 Lite Connected is designed to provide the computational power of the Portenta H7 for AI applications and low-latency control solutions, with a module that is made more cost-effective by removing the high-resolution video interface feature.

It fills the gap between the full H7 and the H7 Lite versions by integrating wireless connectivity, adding yet another option for Arduino Pro clients to build the perfect solution with the right combination of performance and simplicity.

The Portenta H7 Lite Connected simultaneously runs high-level code and real-time tasks thanks to its two processors. For example, it can execute Arduino-compiled and MicroPython code at the same time and have the two cores communicate via a Remote Procedure Call mechanism that allows calling functions on the other processor seamlessly for real multitasking. Your machine learning algorithms can now run simultaneously alongside low latency sensor/actuator interaction.

The Portenta H7 Lite offers twofold functionality: it can run either like any other embedded microcontroller board, or as the main processor of an embedded computer. For example, use the Portenta Vision Shield to transform your H7 Lite into an industrial camera capable of performing real-time machine learning algorithms on live video feeds. As the H7 Lite can easily run processes created with TensorFlow™ Lite, you could have one of the cores computing a computer vision algorithm on the fly, while the other carries out low-level operations like controlling a motor or acting as a user interface. Portenta is the go-to family when performance is key, and the H7 Lite is no exception. We can already envision it as part of a wide range of solutions, including:
  • High-end industrial machinery
  • Laboratory equipment
  • Computer vision
  • PLCs
  • Robotics controllers
  • Mission-critical devices
  • High-speed booting computation (ms)
