Board Information

Provide information about your custom board. This will be used to generate a complete Zephyr board definition.

Board Name* Lowercase letters, numbers, and underscores only (e.g., "my_custom_board")

Full Board Name* Display name for the board (e.g., "My nRF Board v1.0")

Vendor/Manufacturer Lowercase letters, numbers, and underscores only

Revision (Optional) Board revision (e.g., "1.0", "rev_a")

Description (Optional)

Select Pins for Peripheral

Select which pins to use for each peripheral function:

Note: This peripheral supports both Port 1 and specific Port 2 pins. For optimal power consumption, Port 1 is recommended. If using Port 2, only the specifically designated P2 pins for this peripheral can be used.

Export Configuration

This will export your current pin configuration for the selected MCU/package to a JSON file. You can use this file to:

Share configurations with team members
Back up your pin assignments
Restore configurations on a different browser or computer

Note: The exported file is specific to the currently selected MCU and package.
