In a blog post, Raspberry Pi founder Eben Upton explains that "through dumb luck," the same camera connector that the Foundation uses for its development kits just happened to fit onto the right side of the Zero. By moving the surface components a little to the left and rotating the activity LEDs, the team was able to close the feature gap between the Zero and bigger Pi boards.

If you've already invested in a camera module for an existing project, you will need to invest in a new cable. The CSI connector on the Zero is 3.5mm smaller than the adapter on the Pi 3, meaning it can't simply be hot-swapped. But if you're new to Raspberry Pi and are looking for a new DIY project, the addition of a connector may allow you to build a cheap home security system or have some fun making a tiny spy camera.
