“I have had two of these using one as a SHIM and soldering the other to the 2x6 header.
This has to be the best addon for running a headless Pi if you are using Cron* or SSH/VNC.
On and off at the press (and press and hold) of a button.
Although I have given this 5 stars I need to knock 1/2 a star off.
This is because soldering it onto a header (i.e. using it as Shove Hardware in the Middle) is a bit tricky. If you use too much solder you might find it impossible to put a hat/phat on the header (I had to use a file to make things fit). Maybe the brains at Pimoroni need to redesign it using what ever magic they used on the LED Shim! HINT HINT!!
(I do wish that they would bring back the original Black Hat Hacker The mini is too small for a full sized hat and the stack is a bit OTT. Come on lets have the original back ... even if its just PCB only .... PLEASE)

“The one problem I've always come up against with the Raspberry Pi is how to shut it down when used in a headless situation or when the GUI your using doesn't give you an easy shutdown option.
That's no longer an issue with the OnOff SHIM, I quickly and easily soldered on the supplied header and with the one line auto install script I had the OnOff SHIM working with my CNCjs set-up in less than 5min and it works great.
I'm so happy I found these and ordered a couple to use with my Pi's.”
“This shim is great. Worked the first time, works every time. The only problem is that I cannot find a case that fit with the shim on. Does anyone know of such a case?”
“One of my favourite Pimoroni boards (shims). I have had random failures of Raspberry Pi's which seem to originate in switching them off by pulling out the plug. I am slowly adding these things to my projects and so far have not had any similar problems. Nice thing is that the onboard pushbutton works great for prototyping but there is a nice connection available for an external pushbutton when the project is moved to the finished article.”
“a must have bit o' kit if you want to go headless. nice and compact, and cheaper than corrupting a few SD cards.
after I did a lot of reading, I found out, to boot using regular power supply, then disable 1-wire in the raspberry pi configuration tool, other wise the onoff shim will only shut down but not start the pi. don't forget to power though the SHIM, and it works a treat.”
