Omega compatible 2.00mm female pin headers
-
Has anyone found female pin headers that are compatible with the Onion Omega?
I've followed the links in the various forum postings, but none of the suppliers have any in stock, and even if they did, they don't provide anything less that 1,000 pieces minimum order.
I've finished my board design and I'm anxious to get the parts so I can start to build but I can't find the necessary pin headers anywhere.
Thanks in advance

@Mitch-Christensen I am assuming that you are looking for suitable 2.00mm pitch connectors into which you can plug an Omega.
Not easy to find.
As a first thought, I wonder if you would be able to use XBee connectors (e.g. https://www.sparkfun.com/products/8272) though you would need to cut some down since you need 16 pins per side for the Omega and these connectors are 10 pins each.
Then after some digging, I came across http://www.aliexpress.com/wholesale?catId=0&initiative_id=SB_20160829183105&SearchText=2mm+pitch+connector - I suspect you could find something useful there.

I found an 8-pin version at DigiKey:
Two of these per side and you're good (cross fingers). Will pick up a few and report back.

I started a thread on the subject a couple weeks ago :
https://community.onion.io/topic/902/omega-custom-expansionThis is the response I got from Lazar
@Lazar-Demin said in Omega Custom Expansion:
@Fred-Blais Awesome! Care to share some info about what it will do?
Is it an expansionI'll try to be brief:
- Omega female header:
- Surface mount version (like on the Power Dock):
- Part number: NPPN161BFLC-RC-ND
- http://www.digikey.co.il/product-detail/en/sullins-connector-solutions/NPPN161BFLC-RC/NPPN161BFLC-RC-ND/4558093
- Through hole version (like on all the other Docks):
- Part number: NPPN161BFCN-RC-ND
- http://www.digikey.co.il/product-search/en?keywords=NPPN161BFCN-RC-ND
- Surface mount version (like on the Power Dock):
- Footprint and dimensions of the whole thing?
- If it's an expansion: Generally they come in two sizes: the smaller kind (think OLED Expansion, Relay Expansion) and the slightly larger size (Servo Expansion). You can find all of the dimensions in the Mechanical Drawings
- If it's a Dock: Try to make is match the size of one of the existing Docks, depending on how much space you need. The Dock dimensions are also available in the Mechanical Drawings
- Omega2 Pinout
- It will be slightly different, the pins on the right side will stay more or less the same (UART, USB, ethernet, I2C), there will be some changes on the left side

Well I kinda have something workable, with the parts I listed above.
I had to file down the shroud on the 8-pin headers so I could squeeze two together to fit, but it worked.
That said, I still haven't been able to actually boot up the Omega in this configuration, as per this thread.

I found a supplier. Try SamTec part number SQT-116-01-F-S.
I order a batch, they came in last week and they fit perfectly.

@Mitch-Christensen I got these really affordable ones from itead.cc.
I stumbled upon that supplier while searching for RJ45 jacks with integrated magnetics and PPoE pins.

There is also ebay. Look for these items:
10 Pcs 2mm Pitch 16 Pin Female Single Row Straight Pin Header Strip
20Pcs 2mm 2.0mm Pitch 1x16 Pin 16 Pin Single Row Straight Female Header Strip

Has anyone bought the SMD version of the right-angle header pins off from eBay or Aliexpress before ?
Thanks

Bought the female and male pin header from Aliexpress that is compatible with Omega 1 in case anyone is interested.

I just received my Omega2. I started the search for these headers. If you do not want to wait for delivery from China I am pretty sure that these will work and they are much cheaper than the Samteks.

Yes they are two row. Ignore the 2nd row. I'll probably order some and try them out.

Harwin makes these also.
My local supplier (Electrocomp) had stock, at $0.1 each
Long strip with 60pins or more, but just trimmed to size.
(other supplier quoted $10 each and had 2 weeks delivery
so 10000% mark-up ! )
