Omega Custom Expansion

[Fred Blais]

I would like to design my own expansion board and I have some questions :

• I see in the schematic that the connectors are "CONN FLEX 16/SM". Do you have a part # or Digikey/Newark #? (the female header to receive the Omega)
• Do you have a suggested footprint and dimensions?
• Should I consider that the Omega 2 pinout will be the same as Omega 1?

• Is there anybody on the forum that made his own expansion?

@Fred-Blais Awesome! Care to share some info about what it will do?
Is it an expansion

I'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
• 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

@Lazar-Demin thank you very much. I think it would be a good idea to sell these header in your store. They are out of stock on Digikey. Thanks for the links.

I'll send some pictures of my project when it will be finished! I'm sure you'll love it

@Luciano-S. I did not see it. Thanks.
