JTAG Headers missing?

Tue Aug 20, 2013 2:39 pm

The JTag headers (http://i.imgur.com/pPXQmRq.jpg) are not present on my Pi. Is this a different revision or what happened?

They are not necessary on the board (connects to GPU which is not open source), so to get the cost down I *think* they are not put on the latest boards.

Having just quickly checked my Pi's it looks as if that was "dropped" as part of the B1 to B2 board revision (ie. only my B1 board has one).

Yes, jtag headers haven't been fitted as standard for a long time (I know because I keep having to go to the lab to solder one on...)
Not sure why anyone else needs them though...

Okay, I was just wondering why this was because I kept seeing pictures of Pis with them (and i wondered if mine had broken off or i had even had any)
