Some Questions About UP Core Series

I have some questions regarding the UP Core Series hardware specs.

  1. Does Core Series include USB OTG? It doesn't say if the USB peripheral has OTG capabilities the datasheet, but I need an UP SBC with USB OTG capabilities so that my SBC can be come a USB device/gadget. If so, is this OTG for USB 2.0 or USB 3.0?
  2. Are there UP Core Series boards with the connector receptacles (power, HDMI, USB) not included? Such a board would look similar to the Raspberry Pi 4 Compute Modules which do not have receptacles soldered onto the board itself, making its volume profile smaller and more fit for smaller embedded devices.
  3. In order to use the Wi-Fi/Bluetooth connectivity on the UP Core, is there a requirement to use an external antenna with an SMA connector, or is there a patch antenna (PCB trace) on the UP Core that serves as an on-board antenna?

Thanks.
