5-Pack 40-Pin Single Row Female Header Strip – 2.54mm Round Pin Socket, PCB Mount

If you tinker with electronics or build your own PCBs, these female pin header strips are super handy.

You get five strips, each with 40 pins in a single row, standard 2.54mm spacing.

The round pins make for solid, reliable connections when stacking boards or connecting wires.

Great for Arduino shields, sensor breakouts, or custom projects.

They’re brand new, unbranded, and made in China — nothing fancy, but they get the job done.

Just solder ’em on and you’re good to go.

Store them in your parts bin for whenever the next project hits.
