40-Pin Female Header Strip – 2.54mm Pitch (Single Row)
₹8.00 Inc GST
40-Pin Female Header Strip (2.54mm Standard Pitch)
This is a strip of 40 Female Header pins with a standard 0.1″ (2.54mm) spacing. These are the “sockets” that match the male pins found on Arduinos and other breakout boards. They are essential for creating custom shields, protecting your microcontroller’s pins, or creating detachable connections on your custom PCBs.
Why keep these in your toolbox?
- Perfect for Custom PCBs: Solder these onto your board to make components (like an ESP32 or Motor Driver) removable and replaceable. Never solder a expensive chip directly to the board!
- Custom Lengths: While they come as a strip of 40, they can be cut to any size (e.g., 2 pins, 8 pins, 16 pins) to fit your specific project needs.
- Standard Fit: Designed to accept standard square jumper wires and male header pins used in almost all hobby electronics.
Common Applications
- Making custom Arduino Shields
- Socketing ESP32/NodeMCU boards
- Extending connections on Perfboards
- Creating pluggable sensor ports
The Bench Robotics Guarantee
- Verified Quality: Each unit undergoes a strict visual inspection and quality check in our Lucknow lab before packaging.
- Fast Dispatch: Orders are packed and dispatched within 12 hours.
- Bench Support: Verified customers get direct call/chat support for troubleshooting.

Common Questions
How do I cut these to size?
Cutting female headers is tricky! You must sacrifice one pin. Use wire cutters to cut through the middle of the 5th pin (for example) to get a clean strip of 4. Then, use sandpaper to smooth the edge.
Are these stackable?
No. These have short solder tails meant for PCBs. If you need “Stackable Headers” (with long legs to pass through a shield), please check our “Arduino Shield Headers” section.
Will these fit my Arduino/ESP32?
Yes, 99% of hobbyist boards use the standard 2.54mm pitch. These will fit Arduino Uno, Nano, Mega, ESP32, ESP8266, and Raspberry Pi GPIO pins perfectly.
Can I use round jumper wires?
These are designed for square pins (like dupont wires). Round pins (like machine-tooled IC sockets) might be loose. Standard male jumper wires will fit snugly.
