Next steps, update each mpconfigboard.h in /ports/rp2/boards/* with the board's preferred pins. eg.

#define MICROPY_HW_I2C0_SCL (5)
#define MICROPY_HW_I2C0_SDA (4)

#define MICROPY_HW_I2C1_SCL (7)
#define MICROPY_HW_I2C1_SDA (6)

#define MICROPY_HW_SPI0_SCK     (6)
#define MICROPY_HW_SPI0_MOSI    (7)
#define MICROPY_HW_SPI0_MISO    (4)

#define MICROPY_HW_SPI1_SCK     (10)
#define MICROPY_HW_SPI1_MOSI    (11)
#define MICROPY_HW_SPI1_MISO    (8)

As mentioned in #7476 UART1 is currently defaulting to 4,5 which conflicts with the latest PICO pinout diagrams preferred pins.

Theres a PR which allows changing the default UART pins: #7503
Once that's merged, boards can put UART1 on 8,9 and give 4,5 to I2C0 and 19,16,18,17 to SPI0.

By having all UART, I2C and SPI default pins configurable, boards now have the freedom to pick and choose their favourites.

#define MICROPY_HW_UART0_TX  (0)
#define MICROPY_HW_UART0_RX  (1)
#define MICROPY_HW_UART0_CTS (2)
#define MICROPY_HW_UART0_RTS (3)

#define MICROPY_HW_UART0_TX  (8)
#define MICROPY_HW_UART0_RX  (9)
