This is another version of a connector, not so universal like the 34-pin one, but with a tap on the green LED, that can be used for the transmission and reception of infrared remote control signals.
It's easier to install and less mechanical work.
Note that it lacks USB and JTAG, so this is not for hardware developers. The 34-pin universal connector may be used to include this functionality if desired.

This is how it looks: (The key at position 5 is a bit hard to see)
HOW-TO implant it:
- Prepare the pins of the header:
Pins 1,2,3,4: leave alone
Pin 5: bend it or cut it off
Pin 6: bend to the left
Pin 7,8: bend to the right
Pin 9,10: bend to the left
