Arduino Portemta H7 Lite Connected

The Portenta H7 Lite Connected packs dual-core performance and onboard wireless into a compact Portenta module, optimised for edge AI and low-latency control where high-resolution video is not required.

Ideal for applications that need simultaneous high-level algorithms and real-time control, it supports TensorFlow Lite inference on one core while the other handles sensor, actuator or UI tasks. Typical uses include industrial controllers, robotics, machine vision (with a dedicated vision shield) and mission-critical embedded systems.
