Hi! I'm using CircuitPython 7.0.0-alpha.5-8-g779b5c185 on a Raspberry Pi Pico.

Despite the Pico's datasheet labelling GP16-19 as default for SPI, GP4&5 as default for I2C, and GP0&1 as default for UART, there is no board.SPI(), board.I2C(), or board.UART() available.

The pinout diagram on Getting Started with Raspberry Pi Pico and CircuitPython seems outdated as it only includes the default pins for UART but not SPI or I2C. The page also states that "The Pico does not label specific pins as the defaults to use for I2C, SPI, or UART connections," whereas default pins for those functions are marked in the datasheet.
