Portenta H7 Board

Portenta H7: Arduino turns professional

The Portenta H7 is a programming board that uses the MKR form factor: compact and equipped with the I2C connector that owners of Arduino MKR boards are already familiar with.

Its microcontroller has an embedded dual-core STM32 processor (two cores running at 480 and 240 MHz respectively and capable of communicating with each other). The board can therefore run 2 programs simultaneously (e.g. Arduino and MicroPython). Programming on Arduino is done using the pro version of the IDE.

In addition, the Portenta H7 has a Chrom-ART Accelerator™ graphics processor for advanced management of an LCD display. This GPU allows you to manage applications in different planes, fonts, etc.

Arduino MKR compatibility

The Portenta H7 board uses Arduino’s new and more compact MKR form factor. This means that some MKR shields will adapt to the board.

In terms of connectivity, this new Arduino board covers a vast field of possibilities: WiFi and Bluetooth 5.1 interface, two rows of 26 connectors to the microcontroller’s I/Os, two 80-pin high-density connectors, JST connector for joining a LiPo battery, USB-C connector for adding various peripherals (mouse, computer keyboard, etc.)... More than enough to develop lots of applications for connected objects, human-machine interfaces, industrial solutions, etc.!
