Could anyone please tell me whether the OnOff SHIM (PIM269) is compatible with an original Pi B (rev 2)?
I do see that it says “Compatible with all 40-pin header Raspberry Pi models” and my Pi B has only 26, but it does also say more generically “Compatible with Raspberry Pi”.
I’m guessing it’s a “no” but just want to be sure, if anyone could confirm 100% please?
Thank you in anticipation.
As far as I know, those 26 pins match up with those same 26 pins of the 40 pin header.
And your only using some of them for the on off shim.

I can’t see why it wouldn’t work?
Thanks for the fast response. I looked at different pinout diagrams and couldn’t make my mind up.
I already have the SHIM, I’m just a bit scared to blow up my first ever Pi from 2012. Sad, I know!
It doesn’t hurt to ask and get a second opinion. As near as I can tell, the pins that count, +5V, 3.3V and Ground are where they should be.
Turns out to be a moot question.
Having not soldered for years but done what I thought was quite a neat job on the header, I did in fact desolder one of the components and obliterate another.
Now I remember why I hadn’t used the SHIM before. Quite why every item that requires soldering isn’t also offered as an (extra cost) pre-soldered version I have no idea. People can enjoy tinkering with hardware without enjoying soldering. Thought I’d give it a try but I’ve learned my lesson.
Back to the drawing board.
Sorry to hear that.
Soldering on a header is a time consuming extra manual step, All the SMT placement and soldering is automated. A pick and place and an oven. Plus, a lot of people like the option of what header they want to use, or not use any extra header. I have a bunch of Pi Zero’s with female 90 degree headers on them. It lets me plug them directly to a pHat Stack etc and skip using the ribbon cable.
Good soldering takes time to learn, its an acquired skill. The tip you use has a big impact on how good a job you can do. Too big a tip and you get collateral damage,
