For the definition of the table columns see the explanation at the table
for Adafruit ItsyBitsy M4 Express :ref:`samd51_pinout_table`.

The default devices at the board are:

- UART 3 at pins PA23/PA22, labelled D0/D1 resp. RX/TX
- I2C 5 at pins PB02/PB03, labelled SDA/SCL
- SPI 4 at pins PA12/PA14/PA13, labelled MOSI, MISO and SCK
- DAC output on pins PA02 and PA05, labelled A0 and A1
