Pimoroni OnOff SHIM for Raspberry Pi
PRODUCT ID: 3581
Description
Add a tiny yet convenient power switch to your Pi with Pimoroni's On‐Off SHIM!
Pimoroni's SHIMs (Shove Hardware in the Middle) are a new range of boards designed to be small,
affordable, and handy. They're just 0.8mm 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.
Usage
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.

Technical Details
Software
Pimoroni 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

to run the one‐line‐installer.
