Beside running Arduino sketches on top of the Arm Mbed OS powering the board, one can also run native Mbed applications, MicroPython or JavaScript programs via an interpreter, or AI workloads using TensorFlow Lite. Furthermore, it’s possible to leverage the two cores on STM32H7 microcontroller by running Arduino code on the Cortex-M4 core, while interpreting MicroPython code on the Cortex-M7 core or vice-versa.

Some applications for Portenta H7 board include high-end industrial machinery, laboratory equipment, computer vision, PLCs, industry-ready user interfaces, robotics controller, mission-critical devices, dedicated stationary computer, or “high-speed booting computation”.

Portenta Carrier

It would be a shame to have all those 160-pin exposed via the board-to-board connectors go to waste, so Arduino also designed the Portenta Carrier board with the following features:

  • Storage – MicroSD card slot
  • Camera – 8-bit LVTTL/2-lane MIPI CSI connector
  • Audio -3x audio-jacks for in- or output of analog sound
    Connectivity and Networking
    • Gigabit Ethernet connect (RJ45) – CNXSoft note: A bit confused since there’s a 10/100M on Portenta H7 board, so it’s probably for future Arduino boards supporting Gigabit Ethernet 
    • Cellular network – NBIoT / CatM1 / GPRS Modem & SIM card connector
    • LPWAN – LoRa via Murata CMWX1ZZABZ LoRa module
    • 2x antenna connectors
  • USB – 2x USB ports
  • Serial – RJ-9 connector for CAN bus, RJ-11 for RS232/422/485
  • Expansion
    • 40-pin GPIO connector
    • mPCIe connector (USB,I2C) for external modules
  • Power Supply – Via external supply, or on-board battery connector
  • Dimensions – SGET eNUC (Embedded NUC) form factor 

That’s the first Arduino board that more like a small embedded computer/gateway with so many options.

Pricing and Availability

The Arduino Portenta H7 board is already up for pre-order and shipping should start at the end of February 2020. The board itself is sold for $99.90, but the carrier board does not appear to be available just yet. You’ll find more information about Arduino’s professional offerings on the company’s website.

That’s an impressive set of features for an Arduino. An impressive price as well by the way. It may actually bridge the gap between pure MCU-based systems and linux-based systems with something still network-capable, a bit smarter, running on low-power. However it also means Arduino is entering a new field where network connectivity also means security updates and the end of the “deploy and forget” approach one can have with an MCU. I’m already hearing some RPi fans claim that a full RPi-based system is more powerful and less expensive, though it can really depend on the final application and… Read more »

This board is very promising. I developped a simpler carrier board than the Arduino official one : https://github.com/Rufus31415/arduino-pro-portenta-h7-carrier-board
