Arduino Portenta H7 + Vision Shield
The Portenta H7 is a powerful development board from Arduino with both a Cortex-M7 microcontroller and a Cortex-M4 microcontroller, a BLE/WiFi radio, and an extension slot to connect the Portenta vision shield - which adds a camera and dual microphones. At the moment the Portenta H7 is partially supported by Edge Impulse, letting you collect data from the camera, build computer vision models, and deploy trained machine learning models back to the development board. The Portenta H7 and the vision shield are available directly from Arduino for ~$150 in total.
There are two versions of the vision shield: one that has an Ethernet connection and one with a LoRa radio. Both of these can be used with Edge Impulse.

To set this device up in Edge Impulse, you will need to install the following software:
- 3.On Linux:
- GNU Screen: install for example via
sudo apt install screen.
With all the software in place it's time to connect the development board to Edge Impulse.

Use a USB-C cable to connect the development board to your computer. Then, double-tap the RESET button to put the device into bootloader mode. You should see the green LED on the front pulsating.
The development board does not come with the right firmware yet. To update the firmware:
- 2.Double press on the RESET button on your board to put it in the bootloader mode.
- 3.Open the flash script for your operating system (
flash_linux.sh) to flash the firmware.
- 4.Wait until flashing is complete, and press the RESET button once to launch the new firmware.
From a command prompt or terminal, run:
This will start a wizard which will ask you to log in, and choose an Edge Impulse project. If you want to switch projects run the command with
Alternatively, recent versions of Google Chrome and Microsoft Edge can collect data directly from your development board, without the need for the Edge Impulse CLI. See this blog post for more information.

With everything set up you can now build your first machine learning model with these tutorials:
- Download your custom firmware from the Deployment tab in the Studio and install the firmware with the same method as in the "Update the firmware" section and run the
Note that it may take up to 10 minutes to compile the firmware for the Arduino Portenta H7

Flashing failed. Here are some options:
If your error is 'incorrect FQBN' you'll need to upgrade the Arduino core via:
$ arduino-cli core update-index
$ arduino-cli core install arduino:[email protected]
Otherwise, double tap the RESET button to load the bootloader and try again
Press any key to continue . . .
You probably forgot to double press the RESET button before running the flash script.
