Adding USB splitter to the tool head

Sovol SV08

I want to add EDDY probe to my SV08. I don’t like the idea of having another long cable dangling around.

Would adding a tiny USB splitter to the tool head work?

I want to add a tiny USB splitter to the tool head, plug the cable from the mainboard ito it and then plug the toolhead board and eddy to the 2 ports available. The question is - would that work? This is the splitter I have in mind: NFHK PCBA for USB2.0 Ports HUB USB 1 to 2 Splitter with SR Cover for DIY OEM Parts & 3.0mm Cable: Amazon.co.uk: Computers & Accessories

Hi,
It would be surprising if someone had done exactly that test.
But who knows.
You’ll probably have to test it for yourself, but I’m really interested in the result.

Wouldn’t that be a very clean EDDY install? If we could just add a tiny PCB to the tool head and then have EDDY connected with no additional wire all the way to the main board USB that would be great. I hope somebody thought of that and already tried.

I am a bit stuck. I was thinking about hooking cable from the main board to this:

USBhub
USBhub403×292 21.8 KB

and then connecting this tool head board
SV08 pcb
SV08 pcb977×787 70.6 KB

and the eddy probe to the tiny USB hub PCB.

the issue is that I don’t know how to write everything up.

It looks like we have 24V ground and 2 USB data wires coming from the main board to the tool head PCB. The tiny hub needs 5V. Could I leave 24V and GND from the main board connected to the tool head PCB and get the 5V and GND from the uart port on the tool head to the VCC and GND on the tiny hub? Data cables from the main board would be connected to the tiny hub and then from the hub to the tool head PCB.

I would appreciate any comments about my plan for connecting things. Diagram below illustrates my plan.

I would take a very serious look at the BTT 36 CAN bus to replace the toolhead board and have one usb cable only going to the main board.

I am hoping to do this upgrade at some point.

It might, but you are adding a lot of complexity to save two wires out of a USB cable. Are you sure that it’s worth it?

There is a discussion on Reddit covering exactly what you want to do:

So to answer you original question, yeeaah, maybe. Probably not. At least not without having to reroute your power around the USB converter.
