## Application Examples



<div style="text-align:justify;">

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.

<div style="text-align: justify;">

Depending of the Portenta family board attached to the Portenta Hat Carrier, the DIP switch (SW2) must be in a specific position to ensure the correct functioning of the ethernet interface:

- For the Portenta X8, be sure that the ETH CENTER TAP on the DIP switch (SW2) is on the default position OFF.
- For the Portenta X7 or Portenta C33, set the ETH CENTER TAP on the DIP switch (SW2) to ON.
