Topic: Female headers similar to Arduino (Read 9647 times) previous topic - next topic


I am building a little stripboard prototype and I want to use the female headers that are similar to the ones on the Arduino - but not sure what to call them or how to find them (I'm looking on Farnell).

Either that or something similar - I want to be able to stack another stripboard on top of these.


This is the keyword for search (google, farnell, digikey etc):

"40-Pin Female Header"




RS Components refer to them as "top entry socket", finding them on the RS site is like the proverbial needle/haystack etc.


They have to be cut down to size.


RS don't you just love 'em ;D

Actually you can get a range of sizes. Try


I want to be able to stack another stripboard on top of these.

Have a look at the shield stacking headers from AdaFruit.

Thanks for the RS links - have to say that I prefer Farnell - free postage and they deliver stuff next day even if you order it reallllllllly late.

While I like to support the Arduino vendors etc - I must say I prefer to find them direct - it's usually far cheaper even if it takes an extra 10 mins to find.

(not that I can find those bits on the Farnell site)mail


Here's what I found on Farnell




If you do order from RS/Farnell  etc, have a look at the specs/drawings first because some of the headers are not very tall.  


i get my ones from http://www.bitsbox.co.uk/connects.html

where they are called Single Row Sockets, and come pre cut as 2,3,4,8,16 and 25.

And much cheaper then the big on-line stores!


Thanks for that - Bitsbox looks great.


www.coolcomponents.co.uk also does them - useful site


oh pre-cut ones, nice one.

anyone worked out a good way of cutting the 40-way ones to size?  I've tried wired cutters, knife, side cutters, but they nearly always break in a way that means the end contact falls out :-(

I don't know why they can't pre-score them like the male equivalent.


You will always lose one pin with the female headers.  Trying to cut them without sacrificing one means you'll lose 2 instead of 1 (and maybe trash the whole thing in the process).

I use a dremel tool with abrasive cutoff wheel (preferred method) or small sharp diagonal cutters (decent second choice) to cut directly down the center of the sacrificial pin.



great tip!  counter-intuitive, but cutting right on the "sacrificial pin" does it perfectly.
