Oh hey that’s great.
I’ve just noticed similar things on the DFR0140.
They don’t work in a similar way by any chance?
Hey Pix,
They totally can, but it won’t technically work the same. Those are just exposed pins meant as extra access to the supply rails, you could definitely just hook two jumper cables into the two available 5V or 3V3 pin that you’ve pointed out, it would work just fine. But you wouldn’t be able to stick the module into the breadboard in that case, as it would short the 3V3 and 5V rails together.
In the image above, that same thing can be seen circled in green. But the pins circled in red have that little connector on them, which can be moved between those pin sets to bring the supply rails to whichever voltage you need to use.
Hope this helps!

Feels like a bit of a sacrifice for a breadboard power-supply 
I’ll have a think about it.
Followup question.
How do other people use this? Do they just put up with the fact they can only use one rail on their breadboard or have they figured something out? Is there some weird trick?
