Hi @markwkiehl, welcome to the Blues family!!!
Good news for you and your customers…
The Notecard Wi-Fi has a PCB antenna that is integrated directly into the Notecard itself. The U.FL jack on the Notecard is for customers who are mounting the Notecard into an enclosure that would cause signal degradation to the internal antenna and an external antenna would be required.
I think you have everything you need to start prototyping!
Also, we appreciate your feedback, as we are always looking to improve our customers experience.
Thanks, and let us know if you run into any trouble.
