Magnetic standoffs are small devices that are used to mount and hold electronic components, such as Raspberry Pi boards, securely in place. They consist of two main parts: a base and a magnet. The base is typically attached to the electronic component, and the magnet is attached to the surface where the component will be mounted. The magnet is strong enough to hold the component in place, but it can also be easily removed by pulling the component away from the surface.

Magnetic standoffs are useful for a variety of applications, such as mounting Raspberry Pi boards in a case or on a wall, or attaching other small electronic components to a metal surface. They can help keep the components securely in place and make it easier to access and modify the internals of the device. They are also useful for creating modular and easily reconfigurable setups, as the components can be quickly and easily repositioned without the need for screws or other fasteners.
