Pin Headers Male 2.54mm : 2×40-Pin, Straight, Black, 11mm
The 2 × 40-Pin 2.54mm Male Pin Header provides a reliable, industry-standard interconnection method for PCBs, microcontrollers, daughterboards, and general electronic prototyping. This connector strip features two parallel rows of 40 pins each, with 2.54mm (0.1″) spacing — compatible with standard breadboards, female sockets, jumper wires and many modular shield systems. Its straight pins and 11 mm length ensure solid through-hole mounting and adequate clearance above the board for wire wrapping or socketing. The header is molded in black flame-retardant plastic and uses phosphor-bronze or brass pins for good conductivity and solderability. The part is ideal for projects requiring stable board-to-board or board-to-wire connections, as well as stacking or modular expansion.
