Re: Official FutureBit Moonlander 2 Driver and Support Thread
I am using the raspberry pi 4 with 1.5ghz processor and 8gb memory
Ahoy fellow Raspberry Chum!
I have found that my raspberry pi zeros absolutely HATE any usb 3 cable (the blue ones). They will never ever recognize, however when I got a cable from the dollar store, and connected that to the powered Usb hub, it recognized.
I used Raspbian Stretch Lite when i initially set mine up, however it would appear it has now been replaced with "Raspberry Pi OS Lite" , https://www.raspberrypi.org/software/operating-systems/
I like that since it removes excess bloatware and apps that I did not need, and gave a barebones starting point for troubleshooting.
Did you follow the standard old setup instructions on the pi for the moonlander?
This is the tutorial I had followed. https://steemit.com/raspberry/@qctechno/howto-install-futurebit-moonlander-2-usb-scrypt-miner-with-raspberrypi-3
I'd recommend starting over on the Pi image, since it can get all borkled from too many different file versions.
hope it helps!

Still no idea what this L2F part is... But it smells like my old "electronics 101" classroom in here.

That works. 
How do you like the Apollo? I almost got one of those but it just didn't have the H/s I was looking for.
I can't quite make out the lettering on the U2 part. If you can read it, do a search at Digikey.com and it might come up with the part or one that's very similar so you'll at least know what it is.

I get those a lot...

While you're mining with the Moonlanders, do you get a lot of messages like,
Code:
Pool 0 is sending mismatched block contents to us (0 is not 2-3)
and
Pool 0 is issuing work for an old block
and
Pool 0 is issuing work for an old block
I get those a lot...
Usually only get them on certain pools. I set a lower difficulty, added the skipcbcheck and xnsub and it seemed to help too.
Queue length maybe?
Also.. it def says L2F on it. Might be an oscillator or ic chip according to digikey. I was hoping for a ceramic capacitor maybe...but if it's one of those other.. I might just viking funeral them.

Re: Official FutureBit Moonlander 2 Driver and Support Thread
Are they actually making money for you, or is this just for fun?
I ask because I have 2 and have been less than impressed with their stability and function. While I can mine for days at about 2.6 MH/s on each, that's not earning me more than a few pennies worth of coins a month.
I picked up a couple of Antminer L3+ for $99 each and since I'm running an oversized solar panel system I don't have to worry to much about electric costs. At an average of 570 MH/s they're on track to make between $60-90 a month each.
I'm just curious why you want to invest more in them if they aren't really making anything.

Point them at scrypt alt-coins, set it and forget it. The solar thing you have setup is my perfect dream. My apt complex however charges a tiered electric rate.. 0-100 .13kwh, 101-200, .14kwh, 201-300, .15kwh. you see my problem there. So these little guys fulfill my desire to "mine" a few cents, while only costing a few cents. Wife is happy with the minimum noise as well.
I have an apollo also in eco mode, but these moonlanders make great gifts to blockchain curious.
Any idea what that U2 component is?
Re: Official FutureBit Moonlander 2 Driver and Support Thread
Greetings all, I have many moonlanders, and finally, after years of service two happened to crap out around the same time.
No green power lights on either. One of them.. I am certain the component at U2 fried. (The smoke, smell, and melted chip is pretty obvi) the other all visually appears ok. Both were running at stock speeds (600).
Number 1: clearly something went poof.
https://i.ibb.co/PTNg45P/IMG-20210110-152002297.jpg
Number 2: Unknown issue
https://i.ibb.co/b6fzjsm/IMG-20210110-152032116.jpg
Looking for some ideas, or replacement parts?

Re: Official FutureBit Moonlander 2 Driver and Support Thread
I've been having trouble with the miner's reliability...
So far, I haven't been able to keep it going for more than 4 hours.
In this forum the two explanations I've been able to gather are that either the power supply is too low, or the memory voltage is too low. I'm fairly sure the power is enough, because the miner starts (correct me if that is a wrong conclusion), and even though I've tinkered with the memory voltage it doesn't seem to make a difference. Not only does it not last, but it doesn't last in an unpredictable way - it can last anywhere from 30mins to 4hrs.
Any help would be much appreciated!
Hi I have am having exactly the same issues with my 4 moonlanders, externally powered is polar hub 2.5 amps per port. Tried all versions of changing core and memory voltages, but runs for short time 20 mins- 2 hours and then hash rates crash and the HW errors jump,did you ever find an answer for this.So far, I haven't been able to keep it going for more than 4 hours.

Solution I found was to write a script to restart every hour. Had something to do with a memory buffer, but that was on raspberry's. Not sure how it could equally affect a larger computer.
