3.2 DIP Switch
The DIP switch allows for boot mode configuration:
BOOT SEL: When set to ON, keeps the Portenta in Boot mode.
BOOT: When set to ON enables the embedded bootloader. Firmware can be uploaded via the USB port on the
breakout board (DFU). USB-A to USB-A (non-crossover) cable required. The Portenta H7 has to be powered
through the USB-C® connector or VIN.

3.3 RJ-45 Connector
The RJ-45 Connector allows to plug-in an ethernet cable and connect to your network.
By default it is compatible with the Arduino Portenta H7 as the jumper pads are joint with copper.
To allow compatibility with the Arduino Portenta X8 it is needed to cut 2 jumper-pads, located on top of the to
the RJ-45 Connector, below the SD holder, on the left side of the Carrier as show in the following picture.
Ethernet Jumper pads
4 Board Operation
Note: This board is intended to operate together with Portenta H7 (see section 1.4 Solution Overview).
4.1 Getting Started - IDE
If you want to program your Portenta H7 with the Breakout Board while offline you need to install the Arduino
Desktop IDE [1]. To connect your Portenta H7 with the Portenta Breakout Board to your computer, you will need a
Type-C USB cable. This also provides power to both the Portenta H7 as well as the Portenta Breakout Board.
Alternatively, in order to provide power to the USB connectors and the 5V pins, a 5V source must be applied to J8.
This will also provide power to the Portenta H7.

9 / 18 Arduino® Portenta Breakout Board Modified: 14/02/2023
4.2 Getting Started - Arduino Web Editor
All Arduino boards, including this one, work out-of-the-box on the Arduino Web Editor [2], by just installing a simple
plugin.
The Arduino Web Editor is hosted online, therefore it will always be up-to-date with the latest features and support
for all boards. Follow [3] to start coding on the browser and upload your sketches onto your board.
4.3 Getting Started - Arduino IoT Cloud
All Arduino IoT enabled products are supported on Arduino IoT Cloud which allows you to log, graph and analyze
sensor data, trigger events, and automate your home or business.
4.4 Sample Sketches
Sample sketches can be found either in the “Examples” menu in the Arduino IDE or in the “Documentation” section
of the Arduino Pro website [4]
4.5 Online Resources
Now that you have gone through the basics of what you can do with the board you can explore the endless
possibilities it provides by checking exciting projects on ProjectHub [5], the Arduino Library Reference [6] and the
online store [7] where you will be able to complement your board with sensors, actuators and more
4.6 Board Recovery
In case a sketch locks up the processor and the board is not reachable anymore via USB it is possible to enter
bootloader mode by double-tapping the reset button right after power up.
5 Connector Pinouts
The Portenta Breakout Board provides easy access to the pins on the high density connector of the Portenta family.
The Portenta Breakout Board is shipped in a headerless configuration to provide flexibility in using 2.54mm
compatible connectors to meet their specific application.

Pinouts
In cases where multiple channels are on a single header, the first channel is on the bottom part of the header and
the section channel is on the top part of the header. The order of the channel is determined by the silkscreen
markings.
