That is it, and the connector beneath the HDMI port is the same (but mounted) JTAG connector as the RPi2.<p>I don&#x27;t know what is the chip, though.<p>Also noticed a 2-pin header between the 40-pin one and the upper USB ones: it looks like the &quot;RUN&quot; from the Rpi Zero.<p>EDIT: The 2-pin &quot;RUN&quot; header already existed on the RPi2, where the ceramic antenna is now located on the RPi3.
