Arduino® Portenta Hat Carrier
4 / 34 Arduino® Portenta Hat Carrier Modified: 25/10/2023
1 Application Examples
The Portenta Hat Carrier is designed to complement the Portenta family. It provides direct access to the Portentas'
peripheral interfaces, enabling connections to USB and MIPI cameras. Furthermore, it improves the prototyping
potential through straightforward compatibility with a broad spectrum of Raspberry Pi® Hats.
Motion Controller: With the Portenta Hat Carrier, the Portenta X8 becomes an optimal motion controller for
advanced industrial machinery, including industrial robots. Its integrated CAN interface (hardware level) and a
Robot Operating System (ROS) container (software level) empower the Portenta X8 to manage robotic arm
trajectories, while concurrently communicating with all associated electronics, such as motors and sensors.
Audio Quality Test Bench: Use the Portenta Hat Carrier with the appropriate Raspberry Pi® Hat to assess the
audio quality of speakers and musical instruments. This duo facilitates ambient sound monitoring across
diverse settings, including bustling production facilities or public infrastructure.
Smart Building Security: Enhance your building's security with the combined strength of the Portenta X8 and
the Portenta Hat Carrier. Receive real-time notifications in instances of security breaches, establish an
intelligent video surveillance system to spot unauthorized activities, or amplify your access control by
integrating a high-resolution camera with the Portenta Hat Carrier.
Prototyping With Raspberry Pi® Hats: Expand the capabilities of your Portenta lineup with the Portenta Hat
Carrier. Ready for action, it is designed to be paired with an extensive range of Raspberry Pi® Hats, catering to
diverse requirements, from embedded sensing to direct actuation.

Figure 4 shows the power options available on the Portenta Hat Carrier and illustrates the main system power
architecture.
Figure 4. Portenta Hat Carrier power tree
As shown in Figure 4, the Portenta Hat Carrier can be powered in multiple ways:
Through the screw terminal block connector (J9): Accepting a voltage range between +7 to +32 VDC. An
AP63200WU-7 buck converter (U7) then steps down the +7 to +32 VDC VDC input to +5 VDC for the carrier and
any connected Portenta family board. It is also possible to power the system with a fixed +5 VDC using the "5V"
pin present in this block connector.
Via the connected Portenta family board's USB-C® connector: It provides a stable +5 VDC to the carrier and
the connected Portenta Family board.
From a Raspberry like Hat using the 40-pin header connector: It provides a stable +5 VDC to the carrier and
the connected Portenta Family board.
