MicroPython doesn't require explicit sign-off for patches ("Signed-off-by"

lines and similar). Instead, the commit message, and your name and email

address on it construes your sign-off of the following:

* That you wrote the change yourself, or took it from a project with

a compatible license (in the latter case the commit message, and possibly

source code should provide reference where the implementation was taken

from and give credit to the original author, as required by the license).

* That you are allowed to release these changes to an open-source project

(for example, changes done during paid work for a third party may require

explicit approval from that third party).

* That you (or your employer) agree to release the changes under

MicroPython's license, which is the MIT license. Note that you retain

copyright for your changes (for smaller changes, the commit message

conveys your copyright; if you make significant changes to a particular

source module, you're welcome to add your name to the file header).

* Your signature for all of the above, which is the 'Author' line in

the commit message, and which should include your full real name and

a valid and active email address by which you can be contacted in the

foreseeable future.
