Description
Portenta H7 follows the Arduino MKR form factor, but enhanced with the Portenta family 80-pin high-density connector. Program it with high-level languages and AI while performing low-latency operations on its customizable hardware.
Portenta H7 simultaneously runs high level code along with real time tasks. The design includes two processors that can run tasks in parallel. For example, is possible to execute Arduino compiled code along with MicroPython one, and have both cores to communicate with one another. The Portenta functionality is two-fold, it can either be running like any other embedded microcontroller board, or as the main processor of an embedded computer.
Portenta can easily run processes created with TensorFlow Lite, you could have one of the cores computing a computer vision algorithm on the fly, while the other could be making low-level operations like controlling a motor, or acting as a user interface.
Use Portenta when performance is key, among other cases, we envision it to be part of:
- High-end industrial machinery
- Laboratory equipment
- Computer vision
- PLCs
- Industry-ready user interfaces
- Robotics controller
- Mission-critical devices
- Dedicated stationary computer
- High-speed booting computation (ms)
Two Parallel Cores
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 allows calling functions on the other processor seamlessly. Both processors share all the in-chip peripherals and can run:
- Arduino sketches on top of the ARM Mbed OS
- Native Mbed applications
- MicroPython / JavaScript via an interpreter
- TensorFlow Lite
Graphics Accelerator
Probably one of the most exciting features of the Portenta H7 is the possibility of connecting an external monitor to build your own 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 your Portenta board to the one suiting your needs.
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 65 Mbps transfer rate. Bluetooth interface supports Bluetooth Classic and Bluetooth Low Energy. It is also possible to expose a series of different wired interfaces like UART, SPI, or I²C, both through some of the MKR styled connectors, or through the new Arduino industrial 80-pin connector pair. The 80-pin connector pair provides additional features including Ethernet.
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.
