40-Pin Headers (Male/Female)

These are straight 40-pin header strips (0.1" / 2.54 mm pitch) that solder onto PCBs or modules for easy breadboard prototyping with jumper wires. Perfect for first-year engineering students extending GPIO pins on Arduino, ESP32, or custom boards.

Header Details

• Pin count: 40 pins in a single row—standard length for full shields or modules.
• Types available: Male (pins stick out) or female (sockets) for stacking/mating.
• Pitch: 2.54 mm (0.1")—fits all breadboards and DuPont jumpers perfectly.
• Material: Phosphor bronze contacts, black plastic base; tin-plated for reliability.
• Typical use: Quick-connecting sensors, displays, or motors during testing.
