Topic: FutureBit Moonlander 2 USB Hubs Thread - page 3. (Read 4280 times)
Couldn't get the Rpi to recognize them so i have the anker hubs on a win10 computer. Works great for that...
I hate to tell you, there have been reports of anker hubs having issue with the R-pi, I think it is even mentioned in this thread.
Sorry i'm new here, I just bought a pi and two anker 13 port hubs to run 10 ml2's but i can't get all of the ports recognized. Only about half of them on each hub work. Is there any way to disable the unusable ports to free up the ones i need?

Ok so if anyone is interested I'm now selling one of those plugable 7 Port USB hubs on eBay in the UK see the link

I got the sipolar a-400, 12v x 10A = 120 watts.
If you keep your miners @ ~2amps each, you can slot 10. 5A * 2A = 10 watts. That also leaves you with a 20% buffer.
If you push them faster, higher, say 900mhz... ~3A. That is 15 watts each. 15 watts * 8 = 120 watts. Though I think 8 would be pushing it. No buffer.
Seems like the most bang for the buck frankly. The a-200 is only 90 watts(20A*4.5v).... who cares if it has 20 slots, you cant really use them. Even at 10 watts per stick, you could only get 9 on this hub, and I suspect it would be unstable, because again, no buffer.
Aliexpress has this thing on sale for $45... really does seem like the best bang for your buck.

Hi,
I got some cheap USB hubs lying around. I was thinking, instead of using their wall brick power supply, I would just power them up with SATA standard power cable (I will make my own connector etc). It has 3 pins with 5V, each one should give 1.5A, together that's 4.5A @ 5V = 22.5W. How many miners I can power with that? One or two?

Seems like you could power two with that setup.
Thanks, certainly I will try. Providing that SATA power cable will give real 4.5A:)
In few days I will get started, miners arriving soon so I need to be ready.

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.

Hi, for 2 days now. Will see if i could tweak a bit. But 50 watt are quite a lot. I additionally run shortly 852 but one of the miner got 15% Error rate.

I got a TP-Link UH720 and Raspberry PI 3 (Raspian) and ran 4 Moonlander 2 on them. They run at standard core voltage @ 796 MHZ so about 4,5 MH per Moonlander. The power consumption for the hole setup is 50 watts.
Interesting hub find, they don't advertise how many amps per port but they do advertise a 12v 4amp power adapter is supplied. Good to hear you got 796mhz out of this setup on 4 MLD2's -- how long you been running this setup?
Sure.
For not it is more or less not finished it will be looking like this until i have an idea how to fix.
The setup was quite easy. Raspian default installation. Update OS and the PI. Take the arm bfgminer and start running. Nothing special.

That's a nice hub neochi, I like your setup. Can you share a pic the rig in action? How was setting up the RPi with the MLD2s?

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...Ha. I've got 6 up and running, but that adaptor is white hot. Didn't check the meter, but suspect you're right...
edit - Yes, I've got c. 54w running 5 @ 768. Had 63.8w with 6, which is toooo much. Stolen the ebay idea of yours, looks good, and thanks...
Cool - let us know how you get on. I've got 10x of these on the way to (5x left / 5x right) to help with spacing..

eBay Sipolar hub has arrived, running 6 @768 without any fuss. Looks the part, very pleased. Thanks!
Definitely. Each pair of mine on Anker hubs is pulling 30W at the wall. I currently have 6 sticks on 3 hubs and 4 more sticks pre ordered. It would be nice to have a single hub that can run them all at full speed, but it's not looking like such a hub exists.
I have Sipolar A400 with 10 ML2 & another Sipolar A400 with 10 2Pacs. They rate themselves at 12V 10A (120W), but you can't really push them to 120W (more like 100W). I've seen USB HUB that have separate 480W power supply. But if you're getting into that realm and cost, you might as well just buy an Antminer and muffle the sound with an ice chest rig or something.
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?
The highest freq I have got to work was 900Mhz but run at 876Mhz for best hash less HW errrors.
You will need lots of current for 10 @ 954Mhz maybe 150w source power supply feeding the hub.

I have mine set to hash around 4 Mh/s. I have two that may be duds, so until I get those resolved, I haven't tried pushing the frequencies higher. I'm around 744Mhz I think. I get really unstable results going any higher. Not saying you can't do it, but might require more tweaking than I have time for right now.
