On the Raspberry Pi 2 Model B, Where do I plug the Energenie module?

Question

I have a Raspberry Pi 2 Model B. The GPIO pins look exactly like this:

I bought the Energenie Raspberry Pi RF-Transmitter Board. The instructions (https://energenie4u.co.uk/res/pdfs/ENER314%20UM.pdf) show where the board should be plugged in a different model Raspberry Pi.

So there are several potential places I can connect the Energenie board. Does it go

• All the way to the left?
• All the way to the right?
• Does it line up with that "GPIO" which seems to start at the fourth set of pins from the left?
• Or somewhere else?

If someone could take that top image and draw a box around the correct pin placement in Paint or something that'd be amazing.

Answer 1

All the way to the left?

This one (pins 1-26 are common)
I found this fine picture:

Answer 2

all the way to the right (towards the SD card). The first 26 pins on the 26 pin and 40 pin Pi's are the same.

You may have a problem getting it to fit because of the extra pins. You have a couple of options in that case.

• cutting pins 27+28 (the fourteeth row),
• trimming the header to clear the extra pins (not recommended as it may effect the integrity of the mechanical or electrical connection),
• female to male jumper wires,
• stacking headers (which you can remove the interfering pins without damaging the Pi),
• an adapter board,
• a breadboard breakout board.
