Official FutureBit Moonlander 2 Driver and Support Thread

[pyroandy]

This one only has 2.1 amp max per port 10 amp total, still not going to cut it. These Moonlanders need at least 2.5 amps apiece.

As you can see from the pictures i placed, i'm running mine nice and stable at 900mhz, giving 5.1mhash per miner. Amp draw 2.2-2.35

The hub i use states 2.1 amp per port but i have seen power draws of 2.85 while i was screwing around with the mld voltages.(max v core, memory voltage pretty high as well and at 954mhz)

The 12v 10amp power supply is 120watts. The moonlanders 5v2.3amp = 11.5 watt. Even if i'd use all 10 ports thats 115watts and below the 120watt of the power supply. I think you did not notice the hub uses a 12v power supply and the mlds use 5v usb ports?

You are right, I forgot to do the conversion of power from 12 volts to 5 volts. No conversion is perfect 100% most DC to DC converters run around 86-92% efficiency. This is reflected in there 5 volt 2.1 amp per port spec. So instead of 120 watts (12X10), you will only get 105 watts total (2.1X10X5), maximum power. You never want to run at maximum power for extended amounts of time as you do with miners so the 105 watts should be derated by about 10% or so. So this would give you about 1.9 amps per port continually. When really you should have 2.3-2.5 amps per port to run these things full out. One thing I noticed about the Sipolar A-400 Powered Hub is one of the ads on Amazon had a picture of the board inside. That clearly shows five DC to DC converters inside. Each Converter current should be capable of putting out 4.2 amps each. It looks like each converter is hooked up to two ports. So if you only use 5 of the ten ports you can get 4.2 amps out of each set which is way more then enough to run 5 MoonLands at full bore. Here is how they are internally connected inside to each of the 5 DC to DC converters. 1 and 2, 3 and 4, 5 and 10, 9 and 8, and 7 and 6. So if you want to run full bore only use one port of each set.

I have not seen it opened up yet, any chance you remember the site?

I also have a 2nd power supply, rated 150watts. Couldn't i just use that? (In other words, do you perhaps know if the used converters can handle more than 4.2 )

You can see the board here on Amazon; https://www.amazon.com/Sipolar-Desktop-Charging-Station-Charger/dp/B01K4MZQJ8/ref=sr_1_1?ie=UTF8&qid=1521590644&sr=8-1&keywords=sipolar+a-400
If you look at the coils for the DC to DC converters you can see the five converters. I would not think they can take much more than the rated current but you can try.
The next step up is the Sipolar hubs with the built-in power supplies. Here is the 20 port 20 amp A213 model; https://www.amazon.com/Sipolar-Refreshment-Charging-Mounting-Brackets/dp/B01K4JKCYK/ref=sr_1_3?s=electronics&ie=UTF8&qid=1521591094&sr=1-3&keywords=sipolar+a-213
Looking at its board there or no converters on the board meaning that the built-in power supply is probably 5 volts so you can use any combination of ports. This is the 40 amp version; https://www.amazon.com/Sipolar-Industrial-Charger-Refurbish-Cellphone/dp/B01KPOEX9O/ref=sr_1_2?s=electronics&ie=UTF8&qid=1521591380&sr=1-2&keywords=sipolar+a-223
Which should give you plenty of power on all the ports but I don't think you can physically fit 20 MoonLanders on it.

What am i missing here?

zpool has too high worker diff for these to work.. they just time out.

Thanks for your answer. So do i understand this right, even if i throw 12 (like i do) or 1200 MLDs at zpool, they won't get any work?

they'll get work but I'd imagine they'd be highly unlikely to find a share in time

use a pool with a lower difficulty or one where you can set a static difficulty there's a few about

The way i got mine running now is using ports 5+10 and port 9. So they are already connected to 1 converter with ports 5+10 and run great.

In regards to the maximum output of the power supply, i already was planning to plug in 8 MLD's maximum so i won't push the supply to far. (8x12=96 watts)

Once i have the extra MLD's in (shipping takes quite long from Bitshopper unfortunately.. they said 2-4 days but all together it's nearly 2 weeks before i'll have them) i can put the hub to the test and i'll let you guys know. I'm considering getting 1 or even 2 extra USB voltmeters just to see difference in amp drawn on a converter with a single MLD on it vs 2 MLD's on it
I just order 2 extra USB voltmeters... What can i say, i like tinkering and patience is not my strong side

All up and running, Odroid XU4 works fine with the compiled arm v6 binary absolute breeze to set up haven't started playing with settings yet gonna leave them for 24 hours see how they do beforehand.



Got 3 units plugged into a 7 port 60w and 2 plugged into the 10 port 36w, so they should all have enough power. It's a bit messy, I'll need to order a hub that can run all 5 maybe 10 soon.

[edit]
switched pools, reduced hardware errors and rejects quite drastically

Good!

You're running them at 600mhz now? The HW/errors usually go down a little bit over time

Which pool are you using and what coin are you mining? Which hubs are you using now?

[thestockfadi]

I've still yet to figure out how to set a "failover" pool  . .I did a bit of googling and found a thread talking about setting up the BAT file a certain way?

bfgminer.exe --scrypt -o stratum+tcp://lycheebit.com:3433 -u iZBPmJNw6Mog42k8P9zvPtYkTwcU1gRir4 -p c=IC,d=128 --failover-only -o stratum+tcp://stratum.miningpool.shop:20004 iZBPmJNw6Mog42k8P9zvPtYkTwcU1gRir4 -p c=IC,d=128  -S MLD:all --set MLD:clock=832 pause


Mr. Stfano? Can you assist in this matter for a failover pool? POr is there an internat setting in BFG miner?

yea just at 600mhz they've been running fine all night at an average of 3.3mh with around 1% hardware errors.
I'm over at miningdutch atm I was on there multiport but switched to netcoin (low diff pos) it was bouncing around too much on the multipool port but looking at my script I didn't set a difficulty so i'll try there again later.
Probably a dumb question but with difficulty is it best to combine the hashrates of the sticks(15mh+) and set a higher difficulty or use the individual hashrate(3.3mh+)?

I'm using an Orico 10 port 36w for 2 of them, this one I'll definitely replace due to size, vibration and low power but it'll do for a while after that I can use it on my desktop
https://www.amazon.co.uk/gp/product/B00KBT8DUY/ref=ox_sc_act_title_1?smid=A103TZ89DUFDUW&psc=1
and a pluggable 7 port 60w which has 3 in
https://www.amazon.co.uk/Plugable-SuperSpeed-Charging-Adapter-Support/dp/B00RNFY8HQ 

the real test on whether the hubs will do for now will come when I start changing settings and they pull more juice

I got in the 2 additional USB voltmeters today, so the MLD's had a quick 1 minute break after 3 full days of mining at 900mhz:


With the 3 voltmeters attached, the one that says 'full"(and with long runtime on it) is the one i already had installed. The others are new.

Amps stay around 2.18-2.35 while running at 900mhz

I should really get one or 2 of those

managed to get 3 going at 768 but the 2 in the 36w wont go past 700 without just producing hardware errors or failing to start

I've ordered your recommended hub at ali express but chose a faster delivery option, watch me get import tax   probably order a few more of these in a few days and make better use of it

Yes sir! The 2 that point sidewards should share 1 converter according to the picture from the amazon site you send me:

And the one that sticks out upwards has it's own converter.

I just took another pic, on which they've had the chance to run for a while:

The one sticking upwards just had a spike on this pic, up to 2.55amp. Besides that, it runs on 2.20-2.35 amp just like the other two, which also every now and then have a quick spike in amp draw but then immediately turn back down to 2.20-2.35. It seems to happen more when they run warm/hot. (one of the fans still is not functioning properly, and it's the one that was supposed to cool the one MLD thats sticking out upwards.)

You have cranked up the voltage of the vcore to get to 768? Or have not done anything with core voltage yet?
This is the usb voltmeter i have:

As you're dutch too, that one is shipped same day

your 36watt hub should provide enough power for 2 MLD's... Maybe try separating the MLD's a bit more, in case that hub uses dc-dc converters in a setup like the sipolar hub?

not yet I need to get a battery for my multimeter, lent it to a mate and he left it on.. typical.
I'm British they had them in Maplin a little while ago and as they're having a closing down sale I'll check there
I'll give that a go, I've got one in the first port and one in the fifth at the moment I'll switch 5-10 and see what happens 

[Finless]

ScoobysportD, so what is your average Vcore voltage to run them that high?
I can not seem to get past 832 clock on both mine with a good PS and fans keeping the rear heat sink cool.
When I get to 852 I get too many hardware errors (30% or so).  Vcore I have tried up to 8.2 but did not want to go any higher.  I assume you are runing higher than that?

Thanks,
Bob

My bad! Thought i read some where you were dutch and that coupled to the dutch mining pool.... let us know what happens when you switch the MLD vs usb ports.

Got in a multimeter todat, will try to get some readings tomorrow! My guesstimate would be around .85-.87

That's good to see. At least we know they can do more than the 2.1 amps per port they are rated for. I just hope it lasts.

Hi Bob,

I just measured them:
2 run at 0.8vcore, 1 on 0.82. Not bad for eyeballing it with such sensitive pot's! This close up is of the one running at 0.82 and this one draws the highest amps of the 3 i have now. This should give everybody an idea/starting point on how to set vcore and memclock.

They've been running basically for 4 days straight now with low error rates as you can see in my previous posts.

Yeah, so far that has not been an issue. I'm just... Reluctant to stop mining to open up the HUB to see if i can find any serial # or something to identify those converters to check the specs...
