Pin header

A pin header is like a little Lego block that helps electronic things talk to each other. It's a tiny, rectangular piece with lots of metal pins sticking out of it that fit into little holes on a circuit board.

Think of it like a puzzle piece with a bunch of little metal legs on the bottom. When you connect the pins into the little holes on a circuit board, everything becomes connected and the electronic devices can start working together.

In other words, it's like a bridge that allows different electronic devices to communicate with each other for a successful operation.
