Arduino Portenta H7

Added to your shopping cart

Arduino Portenta H7 is a dual core unit that features a 480MHz Arm® Cortex®-M7 and a 240MHz Arm Cortex M4. This allows the Portenta to run high level code with real time tasks in parallel. For example, it's possible to execute Arduino compiled code along with a MicroPython one, and have both cores communicate with one another. The two cores communicate by a remote procedure call mechanism that allows calling functions on the other processor seamlessly. The Portenta can run like any other embedded microcontroller board, or as a main processor of an embedded computer. Use the Portenta Carrier board to transform the H7 into a eNUC computer and expose all of the H7 physical interfaces.

Two Parallel Cores The H7's main processor is the dual-core STM32H747 including a Cortex® M7 running at 480 MHz and a Cortex® M4 running at 240 MHz. The two cores communicate via a Remote Procedure Call mechanism that seamlessly allows calling functions on the other processor. Both processors share all the in-chip peripherals and can run Arduino sketches on top of the Mbed OS, native Mbed applications, MicroPython/JavaScript via an interpreter and TensorFlow Lite. With TensorFlow™ Lite, one of the cores could compute a computer vision algorithm on the fly, while the other could make low-level operations like controlling a motor, or acting as a user interface.

Graphics Accelerator The Portenta H7 has the possibility of connecting an external monitor to build a dedicated embedded computer with a user interface. This is possible thanks to the STM32H747 processor's on-chip GPU, the Chrom-ART Accelerator™. Besides the GPU, the chip includes a dedicated JPEG encoder and decoder.

A New Standard for Pinouts The Portenta family adds two 80-pin high density connectors at the bottom of the board. This ensures scalability for a wide range of applications by simply upgrading the Portenta board.

On-Board Connectivity The onboard wireless module allows to simultaneously manage WiFi and BLUETOOTH® connectivity. The WiFi interface can be operated as an Access Point, as a Station or as a dual-mode simultaneous AP/STA and can handle up to a 65Mbps transfer rate. The Bluetooth interface supports Bluetooth Classic and BLE. It's also possible to expose a series of different wired interfaces like UART, SPI, Ethernet, or I2C, through some of the MKR styled connectors, or through the new Arduino industrial 80-pin connector pair.

USB-C Multipurpose Connector The board's programming connector is a USB-C port that can also be used to power the board, as a USB Hub, to connect a DisplayPort monitor, or to deliver power to OTG connected devices.
