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.

Low cost and works great with Retropie running from battery but needs support for Recalbox! Pimoroni please add Recalbox support. You can probably modify the existing powerswitch.sh script in Recalbox.

Handy little addition to any pi

Nice neat little board perfect for one of my projects. My only suggestion would be to include an insulative pad to prevent the SHiM shorting to the Pi if soldered too close/knocked.

I'm using this on a Raspi3 for my boat running Open Plotter and had some issues at first because I had the 1-wire buss enabled. Thanks to the Pimoroni Forum I was able to make it work by turning the 1-wire buss off in the Raspberry Pi Setup Interfaces tab app and then later move the default GPIO pin for the 1-wire buss to a different GPIO pin (In my case GPIO 23/ BCM 23) and get the 1-wire interface working again so now I'll be able to add temperature sensors for my outboard motor and my livewell as well as have a soft On/Off function like a professional quality device Now I'm going to get another for my Retropie arcade setup

Where's the schematic? I would like to know what I would be buying exactly.

I purchased this as its a great idea for my arcade machine. Only reason for 4 stars was that it was a little fiddly to set up the software. I had an 403 error and had to remove a file to get it to install ok. Once it did it worked great!

This is a great idea and allows the pi to boot up easily. however I tried it with a couple of images I had and all would not work, coming up with a 403 error which means the script cant be automatically installed. All it would take is some instructions to manually install and run the script and I've had very poor responce and help. Rather frustrating.
