CONN HEADER 8POS 2.54mm DUAL ROW SMD
The 2.54-2×4P is a generic 8-pin dual-row connector/header with a 2.54 mm (0.1 inch) pitch, commonly used for board-to-board, wire-to-board, and programming/debug interfaces in electronic circuits. The designation 2×4P indicates two rows of four pins, providing a total of eight electrical connections in a compact arrangement.
This type of connector is widely used in embedded systems, development boards, industrial control equipment, consumer electronics, and prototyping applications due to its standard pitch and broad compatibility with jumper wires, IDC cables, and mating sockets.
