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.
* ATSAME54P20A microcontroller
* Embedded Debugger
* Digital I/O - Two mechanical buttons (user and reset button). One Atmel QTouch button. One yellow user LED. Three Xplained Pro extension headers.
