Comparing the photos to my Pi 2, it doesn't seem very different. There's an extra IC near the microsd card, a connector beneath the HDMI port, and a few other small changes.
But nothing that looks like an antenna. Any idea where that might be?
Edit: as lovelearning pointed out, there is a small ceramic-looking piece in the upper-left of the top side, near the GPIO pins and LVDS display connector. That might be it.
- agumonkey 11y agoFirst thing that came to mind. All the wifi ready SBC have a very easy to spot chip and some form of visible antenna. I'm almost thinking the shots were just for gross form factor approximation.
- bravo22 11y agoAccording to FCC report they are using a chip antenna.
- casylum 11y agoLook for a cutaway ground plane as a hint to where the antenna may be. http://imgur.com/a/z9bDR http://imgur.com/a/z9bDR Wifi antenna and chip set highlighted.
- oxplot 11y agoSecond last "internal" photo, top left corner next to the ribbon connector. That thing that looks like a long cap SMD is the chip antenna (just guessing).
- Squonk42 11y agoThat is it, and the connector beneath the HDMI port is the same (but mounted) JTAG connector as the RPi2. I don't know what is the chip, though. Also noticed a 2-pin header between the 40-pin one and the upper USB ones: it looks like the "RUN" from the Rpi Zero. EDIT: The 2-pin "RUN" header already existed on the RPi2, where the ceramic antenna is now located on the RPi3.
- Squonk42 11y agoThere is a big Diode D5 near the micro-USB power connector.
- nfriedly 11y agoAlso worth noting: the new IC and the suspected ceramic antenna are in about the same place on opposite sides of the pcb. So I think that lends some credence to the idea that is is an antenna. Man they can make small antennas these days...
