Comparing the photos to my Pi 2, it doesn&#x27;t seem very different. There&#x27;s an extra IC near the microsd card, a connector beneath the HDMI port, and a few other small changes.<p>But nothing that looks like an antenna. Any idea where that might be?<p>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.
