FutureBit Moonlander 2 USB Hubs Thread

[markcarline2]

Update - I got this email from pluggable support about their 7 port usb 2 / usb 3 hubs:

Thanks for asking. The person in that forum is correct, there are three 12 to 5V buck converters that all share the same incoming 12V from the power adapter on both our USB2 and USB3 "HUB7BC" models.

We've done load tests drawing nearly the full 60W the power adapter is rated for spread across all ports (about 1.5A per port) and did not have any issues for normal USB devices, but depending how much power these miners each pull under load and when overclocked, I suspect that three on one buck converter might be an issue as the poster in the forum ran into.

If you were to split all 7 ports up equally and assuming 100% efficiency you could in theory draw about 1.71A per port. However, there will be some efficiency loss in the 12 to 5 step down and also as the load increases you will in turn run into some voltage drop which is what I suspect was the issue. The miners probably can't tolerate lower voltage, especially when overclocked.

I can't think of a reason why our hub could only power three, from our testing I'd expect if you got a hub, perhaps 5, maybe 6 would be OK running 24/7 at maximum load. But this is all pretty out of the normal use case scenarios for our hubs.

I know this isn't a perfect answer, but perhaps try a hub out and worst case if it doesn't work for your needs we can offer a return for a full refund. For all we know maybe that person had a defective hub, it's rare but does occasionally happen!

Anyone able to try 7x moonlander 2 on one of these hubs ?

Just to help out, I did a test for you.



You can't fit 7 in one anyway, since the fans stick out.

Awesome, I wonder though if 4x usb extension cables could be used on the unused ports?

That one I can't help much with - don't have an extra extension cables to try.

Yes, extension cables should work fine, as long as they are under a foot or so.

So what kind of power/hashrate were you able to pull?

Okay... so this line

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

... makes me wonder if your were only running two on the hub could you actually see higher than the 1.5A?

Is this shot down by a max on the voltage regulators?

Hello guys

Today I ordered one Moonlander 2 Stick. Now I am looking for a suitable usb hub to run it in combination with a Raspberry Pi 3.
Since I am going to run only one Moonlander 2 is this hub possible to use?

Or is there a better option to run 1 Stick?
Thanks a lot.

My first moonlander 2 just turned up ! all working. This is a picture of my setup:

https://imgur.com/a/U68EH

Consists of:

1) Raspberry PI 3 with official Rapsberry PI 3 power supply
2) Cheap USB 2.0 7 port hub - Pluscom Model u7PH-3A (not using the power supply as the Pi seems to be enough for this) cascaded into:
3) Plugable USB 3.0 7 port Hub (inc 12V 5A 60w psu) - Model: USB3-HUB7BC

3 more are in the post in the way so will be testing more plugged into the same when i can (going to try and do 7x all at the time time via extension cables)

Been running now for about an hour now litecoinpool reporting hashing at 3,498kH/s (so far so good!)

Boom!

[radeone]

I couldn't get one I really wanted to play with the damn thing but they were sold out so fast.

[aballen]

Thought I would share this one.  Relatively cheap if it works as advertised.  7 ports, 4amps, I figure you can get 4 moonlanders on it using alternating ports.

Now I just need a few moonlanders 😭

I'll post some feedback once I use it.

[soifigured]

ok yep thanks - I can see from the specs:

The Sipolar A223
http://www.sipolar.com/page172.html?product_id=166
Quote: "Rated Output 5V 2100mA"

Where the Sipolar A200:
https://www.aliexpress.com/store/product/USB-2-0-20-Port-Industrial-High-Power-Charger-Hub/1938705_32641188575.html
Quote: "Rated Output:5V 650mA"

Oh well - none of them are any good i think

I've seen this one mentioned on this forum (but not sure about Moonlander 2) which i might go for:

Plugable USB3-HUB7BC
https://plugable.com/products/usb3-hub7bc/
PSU: 12V, 5A
Quote from link : "USB over-current protection supporting up to 900mA per port (up to 1.5A for BC 1.2 devices)"

I'm also running the sipolar A-223, it works well when filled with 12 moonlanders.  According to the spec sheet it should a moonlander in every port if you run the moonlander at 5w.  Granted you would be running at the upper limit of the included power supply, so 12 is a good amount with a decent amount of overhead.

If you are just running one and have at least 1 PCIe x4 (x8 or x16) slot you can try this. (I am running it on Windows 8.1 Pro. in a x16 slot.)  Two will not fit due to the width of the circuit board, but it is doing 2A to the USB slot. It says it will do 2A to each USB slot.

Trying out a few hubs from Amazon here. I only have 2 sticks so far.

First this Orico: https://www.amazon.com/gp/product/B071FNC3VY/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
Was only able to run both at 600mhz, any higher and at least one would stop hashing after a few minutes.

Next the Pluggable: https://www.amazon.com/gp/product/B00RM5OF70/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
While using this one I initially ran one stick at a time while upping voltage until they were nearly error free at 900mhz. Then I tried both at 900mhz. Every time one would stop hashing after a couple of minutes.

Finally this Anker: https://www.amazon.com/gp/product/B00VDVCQ84/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
Rock solid with both running at 900mhz. I wish I had more of my stick orders in to see how it does with more sticks on it, but I will soon enough.

[aarons6]

the anker hub it says only 3 of the ports supply the 2.1a?

also im not real fond of my pluggable hub i just got.. same as the one you have.

it has some auto switching power thing and sometimes it just turns off and you have to push the button to turn it back on..

I have only 1 moonlander at this time, but using https://www.sitecom.com/nl/usb-30-fast-charging-hub-4-port/cn-085/p/1725 for 3 days now.
It is running flawless :-) Using 1.7 amp at 5 Volt on 756mhz setting.

Update ---- 101202017
Running clock set at  756 hz and using 1,7Amp 5V hashing 4,2Mh/s ---running flawless .06% error rate
Running clock set at  823 hz and using 2Amp 5V hashing 4,7Mh/s.  ---running flawless .17% error rate
With default voltage setting on de stick


Just info...

Those 3 ports are charging only ports, so not using them. Clearly getting pretty good amperage on the others so far to be running stable at 900mhz. HW error rate is consistently lower on the Anker than the Pluggable also, so I guess this is an indication the power is cleaner.

Will be interesting to see how the Anker 10 Port USB 3.0 Hub handles 3 or 4 (perhaps more if you can fit them with a USB cable) all at once.

Pity about the Plugable 7 Port USB 3.0 Hub - have ordered this one. If I face the same issues I will be requiring a new USB hub to handle 7 Moonlander 2's and am currently looking at the below options:

• Anker 10 Port USB 3.0 Hub - https://www.amazon.com/dp/B00VDVCQ84/
• Dyconn PowerHub SuperSpeed 12 Port (10 Data/Charging + 2 Charging Only Ports) Industrial Grade USB 3.0 Hub - https://www.amazon.com/dp/B013XFG9CQ/

Thanks for the reviews.  For the USB hubs that have dedicated power charging ports, has anyone tried a usb y power injector cable to use the power from the charging port and the data from one of the data ports?  Like this one:

https://www.amazon.com/Black-Female-Extension-Mobile-CableCC/dp/B00ZUE6PVE/ref=sr_1_6?s=electronics&ie=UTF8&qid=1512917299&sr=1-6&keywords=usb+hard+disk+cable+power

I think I'll get the 10 port Anker as it can already support 3 and probably three more with cables like above.
