Pycom 2.54mm short headers link to buy some

[Charly86]

Hi there,

I designed a board for a customer using a Lopy and after soldering my 2.54 female headers I realized Pycom use short ones that is a far better option for me, height is lower.

But I can'r find them, do you know where I can source them, male and female ones (SMD and PTH)?

Any full reference or link where to buy them will be appreciated Thanks for your help.

I’m trying to find out, but in the meantime this seems to be the best answer https://forum.pycom.io/topic/1726/lopy-pcb-female-connector/4

Thanks, I searched header and not connector, missed that post.
But with ref BG095, found this one (but 10 pin max) so using 2x7 pins should do the trick

And also ordered this one on ebay

but I'm unable to find the male ones

@charly86
The team suggested this one for female side

@jmarcelino Thanks,
That's expensive, may be buy the 30 pin and split in 2x14 pins is cheaper but it's nice to know we have a reference ;-)

@loboris
I have female rounded (machine) pin headers like the ones you posted but Pycom boards (with the default soldered headers) don't fit on them

[Charly86]

@jmarcelino I've built 10 boards with this reference, unfortunately this is not a good one, it works but:

• It's really expensive
• it's mainly for rounded male pins, so you need to force much more to insert/remove PyCom devices
• and last but not least, it's not the correct height size so when plugged here what it looks like
  

So I'm trying to ask back, anyone in hardware team can just tell us where do they source the connectors and give us official reference or at least put them in the shop?
Thanks

We provide the specs for the headers to our manufactures who then source them via their own channels.

Hello @Charly86 tomorrow I can show you mine headers, bought from mouser. I think they are the same height as pycom ones

@xykon
makes sense, thanks for that precision

[Charly86]

@river mouser link would be awesome, thanks for your help

@charly86 Here is the reference, cost me about 2 hours finding the correct header when buyed and also two failed attempts buying incorrect ones. They are expensive, so buyed 32 pins ones and can be cut to size without sacrifying pins.

As you can see, it's perfect match, BTW the female header it's intended for rounded pins but I feel the module sits more secure with this.
The feel plugging the module on the header it's not bad, not much more force than with Expansionboard.

Thanks for your excellent boards (I haven't bought any yet) but I follow you on another forums and saw your work

[Charly86]

@river Thanks I didn't even thought about IC pin headers, good idea, will try them for sure.
You're welcome for the board, looks like IoT world is still small ;-)
