Using the pi - topPROTO is easy. First, you need to mount it to the modular rail inside your pi - top. After that, connect it via the 34 - pin GPIO on the internal HUB Board. You can also connect other add - on boards to it by daisy - chaining. When building circuits, make sure there's no short - circuit and use the available space effectively. As for maintenance, keep it clean and dry. If you're not using it for a long time, store it in a safe place to avoid damage.
