board – Board specific pin names

Common container for board base pin names. These will vary from board to board so don’t expect portability when using this module.

Another common use of this module is to use serial communication buses with the default pins and settings. For more information about serial communcication in CircuitPython, see the busio.

For more information regarding the typical usage of board, refer to the CircuitPython Essentials Learn guide

Warning

The board module varies by board. The APIs documented here may or may not be available on a specific board.

board.board_id: str

Board ID string. The unique identifier for the board model in circuitpython, as well as on circuitpython.org. Example: “hallowing_m0_express”.

board.I2C() → busio.I2C

Returns the busio.I2C object for the board’s designated I2C bus(es). The object created is a singleton, and uses the default parameter values for busio.I2C.

board.SPI() → busio.SPI

Returns the busio.SPI object for the board’s designated SPI bus(es). The object created is a singleton, and uses the default parameter values for busio.SPI.

board.UART() → busio.UART

Returns the busio.UART object for the board’s designated UART bus(es). The object created is a singleton, and uses the default parameter values for busio.UART.
