OnOff SHIM

Add a proper power switch to your Raspberry Pi with the OnOff SHIM. This ultra-thin board sits between your Pi and its power supply, providing a tactile button to power on and cleanly shut down your system.

Part of Pimoroni's SHIM (Shove Hardware in the Middle) range, at just 0.8mm thick it's designed to be soldered directly onto GPIO pins, leaving room for HATs and pHATs on top.
