PORTENTA H7 – Most Powerful Microcontroller In The Market
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. Use the Portenta Carrier board to transform your H7 into an eNUC computer and expose all of the H7 physical interfaces.
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 BLE. It is also possible to expose a series of different wired interfaces like UART, SPI, Ethernet, or I2C, both 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.

Additional I2C Port
The Portenta H7 has an additional connector meant as an extension of the I2C bus. It’s a small form factor 5-pin connector with 1.0 mm pitch. The mechanical details of the connector can be found in the connector’s datasheet.
The I2C port, also referred to as the Eslov self-identification port within Arduino, comes with: SDA, SCL, GND, +5V, and an extra digital pin meant to send an alarm to the otherwise plain I2C devices connected to it. The pinout is shown in the following image:
