A Pi Zero's big advantage is it's size or lack there of. I want to give up as little space as I can get away with, and be able to connect both a network adapter and a storage device.

So basically I want to keep as much as possible the size/form factor that the Pi Zero gives me.

the one I posted is the same size as the Pi0
the Pimoroni one is slightly bigger but has network in it

You can achieve that without using a hub. Do you have any soldering skills? Two ways to do it:

(1.) USB WiFi dongle, add a (micro) SD card slot to GPIO/SDIO 22-27 for storage.
(2.) USB storage, add SDIO WiFi module to GPIO/SDIO 22-27.

A third option is USB Storage plus wired ethernet on GPIO/SPI, connector alone is a tad bulky though.

The D-Link Hub you posted is very nice, but if I put it on top, of the Pi Zero, it effectively doubles the thickness, and next to it, it doubles the area ... , the Pimoroni one has the issue of the height, caused by the network cable connector. I am if at all possible, wanting to avoid either issue as far as possible - a one box solution is preferable to a two box solution, if it can be achieved, which is what I am trying to ascertain. If I have to go for a two box setup, the D-Link hub would be a neat solution, or for that matter the Pimoroni one.

Your input is appreciated.

Thanks

The first one has a certain amount of appeal :)

Pity that with the second one, the SD card and Wi-Fi, cannot be active at the same time.

The third is not yet available ...

Thanks, they do give food for thought tho ...

PS, my soldering skills, are not great, at the level that the RPi Zero requires, I do, have a friend who's arm, I would have to twist a little to get him to do the soldering. Like me, age, has taken it's toll with both our eyesight ... , :(

If size is so important, why not just get a larger micro-SD card and eliminate the external storage device (and the need for a hub)?

128GB micro-SD cards can be had for under $30 (64GB for under $15), and you can get tiny USB-OTG adapters like these to use with one of the small WiFi adapters.
My mind is like a browser. 27 tabs are open, 9 aren't responding,
lots of pop-ups...and where is that annoying music coming from?

I have my doudts that using one of those - will leave enough space to plug in the power lead, using any of the USB devices I have in my assorted collection - have given them a thought or two. As other "idiots" will be operating the device, if at all possible, I want to try and keep the data and OS separate from each other.

Refering to the types that use CD/DVD writer trays as coffee cup holders etc. The less place the have to plug extras int and try and get "creative" must be limited. So if they remove one the device essential becomes inoperative.

I use this one:-
http://www.ebay.co.uk/itm/Micro-USB-to- ... Sw8-tWVCsG
Micro USB to Network LAN Ethernet RJ45 Adapter with 3 Port USB 2.0 HUB Adapter.
It has an Ethernet port too. :P
Works great and has a mini USB plug so it's just perfect for the Zero.
Can't find the thread you want? Try googling : YourSearchHere site:raspberrypi.org

Hmm... good point. My GF has a Zero, but I haven't tried one of those adapters in it yet. If it does prove to be too big, you could always go with a short OTG cable.

Not sure how that will help when dealing with ID-10-T errors (ID10T), but you could partition the SD card and save the data to the 2nd partition.

Which is all the more reason not to use a HUB. Only power and network adapter. No extra ports, no extra data drive to be pocketed or swapped for something else. What you are saying seems to reinforce my idea, but I don't really know what you are trying to do, so I guess you know what's best for your project.

Java,

Do a google search on "Pogo pin pi zero usb hub". There are several iterations of these hubs that mount to the bottom of the pi zero and use pogo pins to make the power and USB connections back to the pi zero. I think one of these may be just what you are looking for.

The "Hubpixed" ( https://www.amazon.com/Hubpixed-Raspber ... B01EG5MRSM ), which was a Kickstarter a while back, is a caseless 4-port USB hub on a circuit board that screws on top of the Pi Zero. Note that (if I recall correctly) it only works with revisions of the Pi Zero previous to the current v1.3.

The same guy has recently done another Kickstarter for the "HubPiWi" ( https://www.kickstarter.com/projects/17 ... no-cable-c ), which trades one of the USB ports on the hub for built-in WiFi.

Hey, I just tried the little OTG adapter on my GF's Zero and it does leave enough room for one of those small WiFi adapters. I test fit it with a Logitech Unifying transceiver (which is similar in size to a small WiFi adapter), and also with my $4 WiFi adapter (which is longer than most compact WiFi adapters). Both left room to plug in my power cable.

It is a bit narrow there, so I suppose if you had a power cable with a fat plug, and a fat WiFi/network adapter it could collide, but with the parts I use it fits fine.

I could post pictures if you'd like.

Thanks Folks for your insight thus far. You have given me a few options, and some insights that I had not consider or did not know about.

Will be getting a few of those micro USB adapters to test.

Have to play with TightVNC for now - will come back to this - when some "bits" arrive here as well as one of the "new" RPi Zero's ... , have an original - though I doudt the changes are going to cause me any issues.

Much appreciated.
