Add a tiny yet convenient power switch to your Pi with OnOff SHIM!

Our SHIMs (Shove Hardware in the Middle) are a new range of boards designed to be small, affordable, and handy. They're just 1mm thick (the bare board, not including mounted components) and designed to be soldered straight onto the GPIO pins of your Pi, if you wish, so that you can use them with HATs and pHATs on top.

Update: In addition to our regular individual slimline postage friendly packaging OnOff SHIM is now available retail packaged with each OnOff SHIM in its own colourful blister pack, ideal for retail display!


Just plug your micro-USB power supply into the micro-B connector on OnOff SHIM, and then press the button once to switch on power and boot up your Pi. After installing our software (details below), you can press the button again to initiate a clean shutdown and completely cut the power to your Pi.


    super-small SHIM-format board
    1mm thick PCB
    can be used with HATs and pHATs
    corner-mounted push button for on/off
    micro-B connector for power supply
    red status LED
    optional breakout pins to connect an external momentary button
    2x6 female header included
    software daemon to shutdown cleanly
    requires soldering


We've put together a one-line-installer to install the clean shutdown daemon. It watches the state of BCM pin 17 and, when pulled low (pressed), it initiates a clean shutdown. Last thing, just before your Pi shuts down, BCM pin 4 is pulled low to completely cut power to your Pi.

To install the software, open a terminal and type curl https://get.pimoroni.com/onoffshim | bash to run the one-line-installer.
