The Pi Zero and A+ both have what seems like space for an ethernet port on the bottom, in the section labeled J5:

A+Zero

Is this really an ethernet port, and if so, how would one connect to it (provide links to a jack that would fit)?

That's not an ethernet port, it's a JTAG port for debugging.

  • Are you sure? It doesn't look like JTAG. – Coder256 Mar 2 '16 at 19:45
  • Look at the signal names, TRST, TDI, TDO, TMS... – Gusman Mar 2 '16 at 19:46
  • @Gusman Well, shouldn't JTAG have 6 pins (including GND)? – Kachamenus Mar 2 '16 at 19:49
  • @Gusman Those are the JTAG signals. What about them? – Coder256 Mar 2 '16 at 19:51

    Here is the full description on that port: sheffieldhardwarehackers.org.uk/wordpress/2015/12/… – Gusman Mar 2 '16 at 19:53

No it's not an ethernet port (and it doesn't look anything like one either).

It's the videocore JTAG port, that connector is used on all Pi models since the B+ (the original raspberry pi model A and B use a pin header instead). It is used by the engineers who developed the Pi for debugging.

Unfortunately it's not much use unless you have access to broadcom information and tools that are not available to the public.
