Data Storage

Simplify cross-device storage management on Portenta platforms with a single library supporting SD, Flash, and USB storage access.
With this versatile library, you can seamlessly handle various storage types without the need for separate, device-specific libraries. Develop data logging, file storage, or data transfer applications, with a consistent interface. All while reducing development time and ensuring compatibility across the Portenta C33, Portenta H7, and Portenta Machine Control platforms.

This library is compatible with the renesas_portenta, mbed_portenta, mbed_opta architectures so you should be able to use it on the following Arduino boards:

Compatibility Note

Note: while the library is supposed to compile correctly on these architectures, it might require specific hardware features that may be available only on some boards.


To use this library, open the Library Manager in the Arduino IDE and install it from there.
