SAM E54 Xplained Pro
The SAM E54 Xplained Pro evaluation kit is a hardware platform for evaluating the ATSAME54P20A microcontroller (MCU). Supported by the Studio integrated development platform, the kit provides easy access to the features of the ATSAME54P20A and explains how to integrate the device into a custom design.
In addition to ATSAME54P20A, the SAM E54 Xplained Pro Evaluation kit can also be used for evaluating the ATSAMD51P20A microcontroller as both MCUs are identical in pin count and peripherals except that ATSAMD51P20A does not have Ethernet and CAN FD.
The Xplained Pro MCU series evaluation kits include an on-board Embedded Debugger, eliminating the need for external tools to program or debug the ATSAME54P20A. The kits offers additional peripherals to extend the features of the board and ease the development of custom designs.
Note: Not all peripherals are supported by CircuitPython. The Ethernet, CAN, and Q-Touch button are not supported by CircuitPython at this time. Only 16MB (128MiB) of the QSPI flash is accessible via the CIRCUITPY drive.
CircuitPython requires that the board be flashed with the UF2 bootloader. This can be done using the second USB connector, which provides a debug interface. After this has been done once, CircuitPython can be installed and updated in the usual way using the UF2 bootloader, or by using the debug USB connector.

Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.
All previous releases are listed on GitHub, with release notes, and are available for download from Amazon S3. They are handy for testing, but otherwise we recommend using the latest stable release. Some older GitHub release pages include the same binaries for downloading. But we have discontinued including binaries as assets on newer release pages because of the large number of files for each release.
Update UF2 Bootloader
Latest version: v3.13.0
The bootloader allows you to load CircuitPython, MakeCode, and Arduino programs. The bootloader is not CircuitPython. You can check the current version of your bootloader by looking in the INFO_UF2.TXT file when the BOOT drive is visible (FEATHERBOOT, CPLAYBOOT, etc.).
It is not necessary to update your bootloader if it is working fine. Read the release notes on GitHub to see what has been changed. In general, we recommend you not update the bootloader unless you know there is a problem with it or a support person has asked you to try updating it.
To update, first save the contents of CIRCUITPY, just in case. Then double-click the reset button to show the BOOT drive. Drag the update-bootloader .uf2 file to the BOOT drive. Wait a few tens of seconds for the bootloader to update; the BOOT drive will reappear. After you update, check INFO_UF2.TXT to verify that the bootloader version has been updated. Then you will need to reload CircuitPython.
