Is there any getting started instructions for the Giga?
My Giga came with a flexible antenna.
There are no instructions on where to put it.
I "thought" I might use the duo processors for a project.
I have no idea how to program the duo processor using the local IDE.
I saw on the cloud there was a option to choose the processor.
I imagine that option must be on the local IDE but have not seen it.
Thanks for the help.

Documentation for the Giga says J14 is for an external antenna if you set the jumper to use an external antenna. Likely meant to use with a metal enclosure.
Thanks, I saw that but where is J14?
You can see it on the cheat sheet page:
Arduino GIGA R1 Cheat Sheet | Arduino Documentation
That takes a screw on antenna.
The flexible antenna I received has a sticky flat contact.
It would not make contact with the center pin.
There are two flat spots on the back. I bet that is where I am supposed to put it.
Thanks for the help.

Works on my board:
You can find the documentation of GIGA R1 WiFi here
Damm I looked at KurtE's picture again and see that he has the same antenna.
The screw terminal is under the plastic on the end. You would think they could have added a little cheat sheet of instructions.
Now when removing the USB cable I managed to pull the plastic and the screw terminal off.
I guess there is a limit to how many images one can have.
It isn't a screw terminal. It is a standard "U.FL" connector. You press to connect, not screw.
As KurtE mentioned, you must have a bit of care to get it aligned correctly. After that, press down firmly until you feel the connector seat. The connector is quite difficult to remove after connecting so you should be careful if doing that to avoid damaging the antenna or board. It's probably best to plan to just leave it connected. I believe these are rated for only something like 30 mating/unmating cycles (compare that to the cycle rating in the thousands for USB connectors).
I'm sorry to see that. It doesn't appear that replacement antennas are available from the Arduino Store, but this is a very common part you can purchase from any seller of electronics components or online marketplace. Just make sure it is for 2.4/5 GHz and has the correct connector (which most do).
Something that can be confusing when shopping for this connector is that "U.FL" is a trademark of Hirose Electric Group, so every other manufacturer who wanted to make these connectors had to call them something different. This means there are something like 6 different names for the same connector:

Hirose U.FL, I-PEX MHF series, IPAX, IPX,[2] AMC[3] and UMCC (Ultraminiature Coax Connector and Cable Assembly Style A Series from Tyco Electronics)
Thanks for the replies.
Is there a WiFi getting started sketch for the Giga?
Ralph
You are welcome. The example sketch for Wi-Fi on the GIGA R1 WiFi board can be accessed by selecting File > Examples > WiFi > WiFiWebClient from the Arduino IDE menus.
There is a trick to get this antennas on, don't push it flat down.
Angle it at 45 degrees and then push rotate it to 0 degrees, they go on easy as anything.
My antenna seems to be working, at least it connects to my router.
I pulled the press on connector off.
Hello Ralphpdq,
Is your project working properly?
Looking at the photos you posted, I can see a few things that might still cause you a problem. The GIGA pinout sheets say that without an external antenna connected to the Micro UFL the WiFi does NOT work. The part of the external antenna that you noted was a flat sticky piece, that's the antenna. The black cable is just that, a short piece of cable.
I am not sure how you attached the flat flexible plastic antenna to your board. Did you solder it?
In my case, I am using a different antenna configuration -- one that connects to swivel antenna mounted to the box that encloses the GIGA.
Let me know if you are looking for a new flexible antenna. I would be willing to send you mine at no cost.
If you look at the back of the Giga under the WiFi connector there are two pads.
When you expose the sticky side of the flat you see two corresponding pads.
You put the two parts together with the pads lined up.
The flat part is not the antenna! The wire is the antenna.
Everything is working fine, I connect to my router.
Now I am looking for a sketch with a embedded HTML that works on the Giga.
I have a sketch that works on the ESP version.

You can order a replacement antenna from Mouser, part number 538-206994-0100 for $2.10 if you want to get full performance out of your board.
Total fantasy. In your case, the wire is in fact acting as a kind of antenna so it's better than nothing but you have completely misinterpreted how to install it.
Honestly the Arduino factory literature seems pretty poor about the installation of the antenna. If you have access to any internal documents that are more thorough or if the employee responsible for documenting that product could post a short tutorial here. How to safely remove the plastic safety cap from the U.FL connector, how to mate it to the connector on the Giga board and suggestions about where to stick the rectangular antenna based on different board mounting options. One might stress that it is intended to be used with a non-metallic enclosure or without an enclosure at all.
I mention this in case someone should stumble onto this thread and be mislead by some of the misconceptions.
How could I misinterpret non existence documentation?
Why does the flat end have a sticky surface if it is not meant to stick to something?
Why are there matching pads on the Giga and the flat end if they are not meant to go together?
I believe I am getting full performance from the board. It would be interesting to know what performance is expected.
I possible can take it for a walk to see how it performs.
Thanks for the replies.

The flat part is the antenna. The wire is a transmission line.
