Pin defines are: - For Pico define board pins and the default LED pin (WL_GPIO25). - For Pico-W define board pins, external pins and the default LED pin (WL_GPIO0). - For the Nano-RP2040, define board pins, external pins and the default LED pin (GPIO25) - For all other boards, the pins.csv defines the LED pin (if any) for backwards compatibility with code that assumes there's always an LED pin.
WeAct Studio RP2040
The WeAct Studio RP2040 Board is based on the Raspberry Pi RP2040 and can be purchased with 2/4/8/16 MiB of flash.
These boards are available from a number of resellers and often have the name "Pico Board RP2040". WeAct maintain the WeActStudio.RP2040CoreBoard repository containing information on the board.
Build notes
Builds can be configured with the BOARD_VARIANT parameter. Valid variants
can be displayed with the query-variant target. An example:
> cd ports/rp2
> make BOARD=WEACTSTUDIO query-variants
VARIANTS: flash_2mb flash_4mb flash_8mb flash_16mb
> make BOARD=WEACTSTUDIO BOARD_VARIANT=flash_8mb submodules all # Build the 8 MiB variant
flash_16mb is the default if BOARD_VARIANT is not supplied.
Board-specific modules
The board module contains definitions for the onboard LED and user button.
Example:
> import board
> board.led.toggle() # Toggles the state of the on-board LED
> board.key.value() # Returns 0 or 1 corresponding to the state of the user key
