NP. Hub price was really good and has better slot orientation so you can use each other instead of omitting two. Should work good. You're going to face only power and noise issues.

Meanwhile I advice you to find a way how to isolate entire hub from vibrations because fans can go really loud and hub lying directly on table make terrible noise. I had to put a piece of foam underneath to eliminate the contact rattling (and hear only the fans). Best way is remove the original fans and use one bigger to cool them all.

BTW nice mockup, is this 3D? Looking good. Did you made the stick model by yourselves?

Thanks!! The 3d model is my own, though it was done very quickly and is very sloppy. The only accurate things on the sticks are the overall dimensions like width, length, depth, and fan protrusion, heat-sink protrusion, etc.
The rest is guesstimated because I was too lazy to measure or model it accurately.

As for the hub, it arrived today!!! Turns out the box was damaged, but it was actually a brand new unopened unit for 17$ after shipping. Total steal.
I am also happy to report that it is up and running 4 moonlander2's with no issues. Well, other than counter-weighting the hub to stop it from falling off my window sill.
Going to start tweaking voltages too see how high I can get the hash rate on here. but I think this is going to be a very good permanent setup for me.

Glad to hear it's working well. I see some clever solution using cup Wink

... looks like it's moving. Or it's just some optical illusion?

Plugable hub can handle more units (as of the power) but there is limited area around the plugs ... need to use extension cord if you want more sticks.
IMO 25W will be enough to run 4 units at decent clock around 4Mh. You need to test it, see the HW error rate and adjust accordingly.

Thank you very much for taking the time to respond. I have ordered a used unit (Pluggable USB3-HUB7-81X) for $17.
I have mocked it up and it will have no problems fitting 4 moonlanders in terms of physical space. So we will see about the volts/watts/amps.

Mockup below, will report back with more details in the coming week.

I'm running 3 sticks on digitus 10 port https://www.digitus.info/en/products/computer-accessories-and-components/computer-accessories/usb-hubs/da-70229/ ... running fine at 832 MHz ( 4.7 MHs, HW around 1%)

Hub has room to accomodate 6 sticks but you would need to underclock them as the power supply is only 5V 4A.

Hey guys, I am a bit confused as to what gets these things to tick.
How can you be running 3 clocked up sticks at 5V/4A and others cant get 3 working on those pluggable 12V/5A?

Does it really come down to how the board is laid out behind the scenes with the various regulators, etc?

I am thinking of ordering the Pluggable USB3-HUB7-81X: 5V/5A w/ 25W Brick.
They are available used at very low cost, and provide 5w additional over the Digitus hub mentioned above.
Should I be able to run 4 sticks on this sucker at stock clocks? Or is it going to dump out like the other pluggable hubs in this thread.

Well my https://www.anker.com/products/variant/USB-3.0-Aluminum-13-Port-Hub/68ANHUB-B14A has Problems to run 3 MLD2's...

And it's bit crap that it is not working with a Raspberry Pi 3... Or anyone has a solution for this?

hey guys, just wanted to mention this one again. I'm suprised it is not getting more attention. The sipolar a-400

https://www.aliexpress.com/item/10-Port-USB-HUB-Charger-Sipolar-A-400-Standard-20V-6A-Power-adapter/32513481750.html

I think it can handle 8-10 ML2s according to specs, depending on your overclock. Due to the dimensions though, you really max out at 6 moonlanders, with rock solid power @ just about any overclock.

If you want to use all 10 slots, you would have to remove the fans at a minumumm, then you need externals fans, and well, I think you would just be better off buying another hub.

I ordered from aliexpress, and got it in a week.

Been mining on my raspberry pi for over mild oc (4.7mh per stick) three weeks without a single issue. This one is solid, and the price is right.

Anyone tried that kind of ports:
http://a.co/dzWEFEE

This is just standard USB front, with USB 3.0 cable which goes to motherboard. It will give you only what specification says. Wikipedia says that about USB 3.0 power specs:

Quote

Power and charging

As with earlier versions of USB, USB 3.0 provides power at 5 volts nominal. The available current for low-power (one unit load) SuperSpeed devices is 150 mA, an increase from the 100 mA defined in USB 2.0. For high-power SuperSpeed devices, the limit is six unit loads or 900 mA (4.5 W), almost twice USB 2.0's 500 mA.[10]:section 9.2.5.1 Power Budgeting

USB 3.0 ports may also implement other USB specifications for increased power, including the USB Battery Charging Specification for up to 1.5 A or 7.5 W, or, in the case of USB 3.1, the USB Power Delivery specification for charging the host device up to 100 W.[12]

You will get something similar, not more than that.
I tried 2 Moolanders on my USB 3.0 front from my Fractal R5 case. They can work just fine at 756MHz. I wouldn't try anything above that, I don't want to fry my motherboard Cheesy

Thanks for the infos.

I just want to find a good hub that can run 4 Moonlanders 2 and >100$ .. not sure if it's possible

I've two of these, each with 2 ML2s.....

Shared my experience with $25 hub (comes with 20W adapter so could handle 4 MLD2 at decent clock).

Considering doing something like this, except instead of the barrel plug, I'll cut it off and wire it up to the 5v rail of my PSU. Anyone else try something similar, or make custom cables running beefier power wires? Seems like a good idea, then all the ports in USB hubs could be utilized.

Just a quick note for Moonlander folk in UK and Europe - Am currently using this Plugable 7-port hub with x4 sticks, running fine so far: http://[Suspicious link removed]/2zkGMOu

Tried this Orico number: http://[Suspicious link removed]/2jdmoGn failed at more than two.

I have the same setup, you going to try 5x ? Also what speeds you running ?

I'm aiming for 6, 2 more sticks in the post. Running at 720 at the moment, stable, 4MHs per stick. Can obviously go higher, sink temps at mid 60's... Will post what happens with 6!

Ok. I have three more in the post on top of the four I have connected now. I think it's just a matter of speed & amps that each one draws in order to get all seven running. From my post on page two if this thread I think (in theory) we have 1.71a to play with per port...

"If you were to split all 7 ports up equally and assuming 100% efficiency you could in theory draw about 1.71A per port."

What we could do with is accurate amp / speed table for these.

UPDATE (and a WARNING!) : I'm now running 5x moonlanders at clock=756 on the plugable 7 port usb 3 hub and my meter is showing power usage (for the hub alone) at 53.08w, i personally wouldn't like to try running 6x as this will exceed the rating of 60w (12v x 5a) so you're running the risk of overload, over heat / maybe fire etc. I can confirm it's stable though

Time for a new hub...

I'm running 2 Moonies prefectly on that hub at 852 (4.8 MH/s). When I add a third, it craps out. Also, I'm not sure if my kill-a-watt is messed up or not, but it says those 2 Moonies and the hub are pulling 43W from the wall. When I add the 3rd, It reads 64W. Those readings seem way to high. Thoughts?

I got the sipolar a-400, 12v x 10A = 120 watts.

I burned through two of these in two months. Was running qty 10 Gekko 2Pac on one. And qty 10 Moonlander 2 on the other. Both were running about 115W according to Killawatt. Both power plugs are positional now (I have use a zip cord to keep USB HUB powered). I had to stop using one because there is a burning smell every time I power it on.

Any other recommendations? This made in China is really hit or miss. Was looking at Eyeboot but anything 10-port related is sold out.

There's a bunch of Sipolar products on AliExpress, but I'm hesitant to buy more Sipolar after two duds within 2 months of buying them.

Modified Tripp-Lite 10 port hub

Here are some photos of my modified 10 port hub, wire soldered on power
tracks to top of caps solder points.
With the wire mod and 5vdc @ 10amp supply can get 5Mh per unit (Freq=876, D=1024)
This is the max I would set at as cooling becomes a issue and life cycle of chip maybe effected?
Any hub should work long as enough current can be supplied to each usb port to meet the miners demands.

I'm running ten ML2 on Sipolar A400. Prefer Antminer L3+ but too loud to use at home or work. Don't they make mufflers for these things or something super quiet?

Will it run 10 at 954mhz?

I have seen a few sellers that offer a Antminer muffler box. you should look into that

Boy have I got a story for you folks... Roll Eyes

I ordered a bunch of MLDs in November before they were too pricing at $200/each at Amazon and I started to use my rack which has been sitting around for 15 years....finally get to use it.

I went through 4 powered hubs and bought a 20 port Eyeboot from HW (I just got it 2 weeks ago)...One final 10 USB power hub (UNITEK 10-Port Fast Charger USB Wall / Desktop Multi-Port Charging Station ) was working fine until it didn't. Luckily, I was able to get a refund. I use these $6 USB power/data adapters which work fine...

I'm just so burnt out in trying so many hubs..that don't work.
I have 10 MLDs with no home yet.
