header, double-ended male, single-row, straight, 40-pin

A row of header pins, which can be cut to any size (from 1 to 40 pins).These are standard 0.025" square pins, with extra-long tails suitable for inserting into a solderless breadboard.They are compatible with our breakout cables and other standard connectors (e.g. Arduino headers), and are often used as "gender changers" to transform a female header into a male header.
