JST Connector Curved needle 3pin
These 3 pin JST connectors are ideal for projects that have circuit boards stacked on each other. Because of the bent pins, the wires can still plug neatly and easily onto a board that has another board on top of it. It also makes it easy to power one board from the other board when they are stacked on each other.
