I can add the two Arduino Nano header rows, but you only have view access to this project, so I can’t modify it directly.
To proceed, either:
- ask the project owner to grant edit access, or
- fork/clone the project into your workspace, then I can add the headers there.
For an Arduino Nano shield, the usual choice is two 15-pin 2.54 mm female headers, spaced to match the Nano’s two pin rows.
