Is there any way to get another revision or release with a USB-A internal connector put on rather than the flexible ribbon cable footprintā¦I want to put a Sandisk Ultrafit USB on an internal internal USB connector, have the /boot partition be on a smaller cheap SD card just to boot, then have the root paritition / on the USB internallyā¦this way the OS is on a USB which is more resilient and a little faster read/write than a SD.
I got the uHub boards in, just need to order the components then get them SMD mountedā¦
It is how I have almost all my ARM based SBCās setup and they are rock solid and have 64GB or (someday) a 128GB / partition setup
This is how my OpiZero2W is setupā¦

I also have a 1TB ssd mounted externally as wellā¦
I do have PCB design experienceā¦but not on very experienced on kicadā¦
mostly I get others designsā¦and remix/tweak themā¦I will see if I can do a revision with a USB-A connector instead of the ribbon cable oneā¦hopefully I can get it done
I triedā¦ugghā¦ended up removing tracesā¦however was able to get an image of (kinda) what I was talking aboutā¦a full size USB-A connector (thru hole connector might be an issue)

The issue might not be about through-hole itself but whether thereās enough space in this place to fit a USB-A socket. Maybe you could just solder 4 wires from those pads to a socket placed somewhere else?
Also a personal update: I have finally ordered 0.8mm PCBs with ENIG surface finish, will keep you posted on whether it works from JLCPCB 
There is space underneathā¦a guy from YT shoehorned an entire SDR (w/o the case) in thereā¦I showed that the footprint for the USB-A is capableā¦I just accidentally blew out the traces from the power chip to the actual connectorā¦I wonder if if itās a low powered device if the power control chip would even be neededā¦just traces directly from the output of the USB hub IC on the board to the USB-A footprint pads

Iām hoping to add an internal Teensy to my uConsole (which would fit nicely inside the lower cavity) and run m8c to make music. But Iām new to this stuff and skittish about the potential for bricking neat equipment, soā¦
Can anyone provide noob with guidance on what hardware I need to add a short micro usb ribbon cable to the inside of my uConsole via the uHub? Iām especially interested in any plug and play options, because I really do have a talent for destruction with a soldering iron.
Thanks in advance!
Only problem with an internal teensy is that it draws power when plugged in. Youād need a way to disconnect without opening everything up.

Wonder how gracefully this could be done with a tiny switch put in between one of the USBC connectors on the faceplate.
I finally had some time to do first, test soldering of uHub boards that came from JLCPCB for the second time, this time in 0.8mm thickness.
I was a bit nervous as I havenāt done SMD soldering in a longer while, this was my first time using a stencil and a new tiny usb-pd hot plate, so that placing components will be the only time consuming part of the entire process. And oh wow it was, including figuring out the orientation of that SOT666 anti-ESD component which had a tiny ā.Fā marking when I had my microscope and light set really properly.
I was a bit nervous again when it came to installing that first board, as I realized itās thinner than the dummy board provided by ClockworkPi. Fortunately the slots have some margin thanks to spring connectors and - the board works! At first attempt!
This is a testament to how good your design is, @Vitaly . Kudos.
Also tip: folks, if you donāt have the experience or equipment for small component SMD soldering, donāt learn on this board. Buy it directly from Vitaly. It will also be cheaper as you wonāt have to order five boards and multiples of each component!
Two thinga remain, getting that internal connector parts and printing the cover bracket.

@Vitaly is it safe to assume you have another batch of these coming?
I want to try and throw a disassembled Alfa wireless card next to my battery and this ext board with the USB ext ext board you teased would be perfect.
Thanks!
I thought it was 1.00mm thick pcb, although for these sockets usually its a slight range, so should work.
Hey there, just wrote an update here: uPico Expansion Card - #94 by Vitaly

So who here knows what theyāre doing and can get one of these made?
I just placed an order for a few of the uHubs. It is my first time ordering a PCB so once I verify they work and I have a final price I will have some for sell. PM me if you are interested and I will update with a price when I get one.

I ordered PCBs on pcbway and just soldered one. Looks like itās detected, but Iām getting āover-current changeā errors in logs. I checked for shorts visually and with a probe, but couldnāt find any. Iām running uConsole with CM5 if that makes any difference. Anyone have any idea what could be the issue?

My issue is fixed. I soaked PCB in isopropyl alcohol overnight, which probably removed some leftover residue.
I have 4 PCBs left 1mm thick as the original extension board, DM me if someone wants them (in Ukraine).

Awesome!
I did 0.8mm board originally, but 1mm also ok I assume.
