Hello Alex,
I hope all is great with you. Thank you for using the NXP communities.
You are correct, the status of the WCT-15WAUTO13 boards is PRE-PRODUCTION, which means that the documentation is being created and redefined.
Unfortunately, I do not have further information. Have you contacted your sales representative?
In the meantime, have you considered the following evaluation board?
RDWCT-15WTXAUTO
Regards,
David
