JST connector

A JST connector is like the special plug and socket that you use to attach different toys or devices to each other. It is a type of connector with two or more metal pins (like teeth) that fit into matching holes. It's like a puzzle piece that fits together so you can connect things without having to solder them together. This makes it easier to connect and disconnect things, like a battery to a toy car, without having to use any extra tools. JST connectors come in different sizes and shapes, and are used in many electronic devices and hobby projects. Think of them like Lego pieces that snap together to create something cool!
