Agreed. But I doubt that Tuicemen can cram a 3B+ into the battery compartment of his CM15A.

even with the battery compartment completely removed only a zero or zero w will fit inside a cm15. However this isn't why the zero w was chosen for a PiX10Hub the proccessing power is more then adequate for x10 HA  and the price point makes it irresistible for DiYers to get their feet wet in the pi world.

[dhouston]

Costwise, $10 for Zero + HubPiWi-Blue, seems a perfect fit. There is the issue of configuring Raspbian to recognize it whenever Raspian is updated.

I stumbled upon yet another variant on eBay.
https://www.ebay.com/itm/Raspberry-Pi-4-Port-USB-Hub-USB-to-UART-Debugging-for-Raspberry-Pi-3-Zero-W/192745065398?hash=item2ce0804bb6:g:efAAAOSw91VZyQaD:rk:7:pf:0

It connects to the USB port on the Zero or Zero W but gives 4 USB ports plus a USB-to-UART port.

I like the little USB bridge connector.  Here's a US based one with bit more detail.  https://goo.gl/kGtqes

I managed to connect the CM15A USB port directly to the solder test pads using a short piece of a old PC hard drive ribbon cable.
This cleans up the look of my CM15A/pi mod and actualy frees up the OTG USB port for a keyboard/mouse though I doubt it will never get used for much unless I can get my Zwave dongle working on it.
I have ordered a add on board to use in another project for extra ports but feel my small usb hub + ethernet port may be more useful.

I saw same one but not from the USA. One thing is a bit confusing - the USB-to-UART apparently connects to the PI's UART - I'm not sure how useful that would be.

My HubSerialixed - USB Hub + UART for Pi Zero W board arrived yesterday and I hooked it up today.
I really only needed one more port to add a ZWave controller stick to it wouldn't work from a hub with a cm19 or Cm15 attached as well.
However this little add on board works well with both the Zwave stick and the cm19 attached.
Initial tests look promising and HG sees both the Zwave and CM19 first attempt.

Great! My only complaint is with the header used for the UART. I'd prefer no header so end users could add whatever is needed in their specific setup.

[Tuicemen]

I suspect most here won't use the UART header anyways. I also would have preferred no header, I guess if the pins are in the way they can be removed. This has metal offsets and screws and I would have preferred nylon ones for mounting to the PI, guess I can always swap them out.

The hubserialixed-usb-hub-uart-for-pi-zero-w board has actually improved my x10 control via a cm19 even with my Zwave Dongle plugged in as well. That is not something I could say about using a plug in  USB hub.

Using this with a Cm19 was just an experiment as I had plan to use it with a Cm15 eventually.
I doubt my Cm15 control will improve using this addon board but who knows

[Tuicemen]

So today I finally added this into a CM15 it wouldn't fit in the old Cm15A I had laying around but does fit nicely in the newer versions.
The mod only requires cuts in the top cover and battery cover then some filing of the rib on the lowercase where the min usb and HDMI ports are. The battery cover still slides over for a cleaner look.
My CM15 now has Zwave possibilities

@tuicemen - NICE!

[Tuicemen]

Thanks, I used a old top case I had used for several other Board inside experiments. That's why it looks so chopped  up. The battery cover thankfully hides that mess.

That does look nice.
