My Omega 2/2+ dock\new

@Douglas-Kryder Well.. the cause for the led not powering up i think that would be the fact that you have a capacitor instead of a resistor on R5.
But you said that neither the omega is powering on. I'd look for shorts and solder bridges on the board. E.g. on the microusb connecctor seems like that on the first two pins (from left to right in the picture you posted) there is a solder bridge. It will be easy to clean with a solder wick.
Did you tested the regulator in circuit?3.2 or 3.4 wouldn't make that much difference, don't worry.

@valerionew ok, thanks for looking. feel stupid about R5, should have never happened & should have noticed. the short you mention on usb i think was just a small metal tab coming off the top of the metal casing due to photo angle looked like a bridge. but after taking care of R5, power LED now lights up. I will do the headers tonight & report.

@Douglas-Kryder
Check that you have 3.3v on the correct pins prior to inserting the omega in the dock!

Is it available for purchase? Assembled / soldered one.

Check that you have 3.3v on the correct pins prior to inserting the omega in the dock!yes. in my case it is ~3.265v. once i got headers in and checked, put an omega2+ in it powered up ok. i attached a 250GB hard disk to usb and it was recognized then i plugged in ethernet and ifconfig reports it available. at this point decided to take a break from it and will pick up tomorrow or Sunday afternoon. i need to review & read some more. but, thanks valerionew for creating the dock\new and your help as i built my first one. i appreciate it. doug

@Sekar-Pdkt
Contact me via PM, i may have one or two assembled

Today i've done a factory reset. To respond to your question about setup: you'll also need to follow this guide https://docs.onion.io/omega2-docs/using-ethernet-expansion.html#using-ethernet-expansion to set up internet access via ethernet.
-
@valerionew , yes, you are correct. prior to building a copy of your dock\new i had used a simple rj45 dongle thru usb on expansion dock. first tim i plugged it in i was surprised a bit that omega2+ had recognized it but i found that the action on that web page you link was necessary for the dongle so in building the dock\new i assumed it would be necessary but i was not positive. anyway, thank you for mentioning it.

@valerionew Any update on the project?

@Valerio-Backslashnew Any updated on the project?

@Wojciech-Kapelinski The project is released on github, at the moment i'm not planning to do any new version

It is awesome. Functional and small. If your project no need to GPio it is perfect for connectivity. USB + wifi + ethernet.
The next version you can add usb to serial converter for connecting Omega2 on USB OTG.

Good working.
