Overview
Portenta Breakout board is designed to help hardware engineers and makers to prototype and help test devices connections and capacity within the Portenta family boards (e.g. the Portenta H7).
It makes all high-density connectors’ signals individually accessible, making it quick and easy to connect and test external hardware components and devices as normally needed during development in the lab.
Target areas
Prototyping
Application examples
This product is designed to work alongside the Portenta family. Please check the Getting Started guide of your Portenta board.
Product Development: The Portenta Breakout board reduces development time for industrial grade solution automation based on the Portenta line.
Technical Education: The Portenta Breakout board can act as the first point of entry for technician education in industrial grade control and embedded systems.
