Hey, right now the project looks like this:
Schematics and extra docs here:
http://www.danielandrade.net/onion/onion_dock_v0.1.pdf
For 3v3 regulator, I am using a TLV1117LV33DCYR from Texas.
Don't really need so much power from the Traco.
Any extra tips and ideas?
Thanks!!!
Just sent the first board to production.
Going to CES and taking some holidays. I will be back in mid-january.
If everything works I will post here and I can send them to anyone with production + shipping cost 
Hey guys, so I just got my Onion2+ but of course I forgot to buy the dock...
Because I am living in Germany, I think it will be faster and cooler if I develop my own open-hardware onion-dock.
Looking on the schematics of the dock from https://github.com/OnionIoT/Onion-Hardware/blob/master/Schematics/Omega-Mini-Dock.pdf I wonder how important is the component Q1 as I am thinking in having it always on while the micro-usb is connected.
Second questions, could anyone suggest a component for items D12, D13 and D14?
I will use this thread to show the progress.
Cheers

Thanks, but I believe that the AO3401 is also not really necessary, right?
I am almost done with the project, then I will share it here for you to take a look.
