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.

Lets make a programmable guitar pedal, using all the power from the Arduino DUE board with 12 bits ADCs, DACs and RAM memory.

As a continuation from his previous Arduino BASIC interpreter project, Stefan Lenz wanted to take things a step further by recreating a home computer from the 1980s with an Arduino Due board and just a few other components. His system combines a 7" 800 x 480 TFT screen, an SD card reader acting as the disk, and a PS/2 port for connecting a keyboard. He began by mounting the TFT display shield to the Arduino by slotting it in place and inserting an SD card to function as the external disk since floppy drives have long since disappeared and would be far too unwieldy. After soldering some additional wires to the SPI and I2C bus pins, a level shifter was attached to two digital pins that serve as the data and clock lines for the external PS/2 socket. Most of the “magic” in this project comes from the programming which handles everything from reading inputs to showing graphics on the LCD and even interfacing with other peripherals over either I2C or SPI. All of the code needed for this retro home computer can be found here in Lenz’s tinybasic repository, which contains a plethora of example projects and demonstrations that can be run/modified.
