Hello,

I have a Full Node Apollo 2 (TWO) and I want to specifically use it as a Standard unit. In fact, many things have broken except the hashing - web interface doesn’t work, there is no longer a disk drive installed nor an SD card hosting the operating system. I don’t wish to fix any of these things, I simply want to plug it into my Raspberry Pi like my other standard units. Since there is no micro-USB on the Full Node as an output, how do I physically connect it to the Raspberry Pi in the same way as a Standard Unit?

Thanks!

Have you reached out to support for the issues with the controller? Sounds like a simple reflash of the SD card should fix these issues.

As for "converting" a full node to a standard USB unit, you would need to connect our custom 4 pin USB connector to micro USB converter on the hashboard, and remove the controller connector.

I guess we could sell these cables individually if people are upgrading and want to run these off an Apollo III or other controller directly, shoot an email to support and ill let them know we can offer these.

So i have a Apollo ii full node i got second hand. The node and everything works but the miner never hits advertised hashrate. Not even close. On eco i get around 5th, on balance around 6.1th and on turbo i only get around 6.4th. Doesnt matter what i do it just wont climb any higher. Temps are upper 60s, and i have zero errors. Is this just a bad unit or am i missing something? Would love to get advertised TH out of unit. Is there a log or something i can check for issues? Thanks in advance!!

run it on eco mine solo and call it a day.

what should you get with eco about 6th if I recall.

Yea my plan is to run on eco anyways but was just curious if the unit has issues. On eco im right a 5th, never goes above.

its used and it has an issue . why here is why his gear does about 90 to 105% of its rated numbers.

In your case 6th low speed is doing 5th which is 83% of rated number not terrible but off.

the other numbers are far far worse .

here is hoping you paid cheap and will run it a low speed.

it is likely out of warranty and may not be restorable at all.

but check the power you are using at 5th see if it is pulling under 200 watts or over 300watts

use a piece of gear like this to check


https://www.amazon.com/gp/product/B00009MDBU/ref=ox_sc_act_title_1?


if it only pulls 200 watts at 5th its okay for used old gear.

if it pulls over 300 watts at 5th it is pretty much shot.

There were two "variants" of the Apollo II made...early units shipped with the full speed hashboard (about 6 in eco). Last units sold shipped with lower quality asics which was about 5 so this is in line (they were sold as discounted units). Balance and turbo should be higher though for those though.

Im guessing its the later units, its 5th on eco, and maxs out at about 6.5 regardless of setting. the serial ends in -E and i think those where some of the last units if im not mistaken. Is what it is and ill just run on eco or even lower. Really wanted it for the node and solo pool. I got it at a good deal so im satified. Dont think its internal extra 5th is a big deal when i have over 3ph pointed at it from other local machines.

Congratulations to Wilson for mining block 973262 with a 147.7T share!

That ranks 3rd on the all-time FutureBit list of highest-difficulty shares that successfully found a block:

1. 888737 — 393.7T
2. 867760 — 186.4T
3. 973262 — 147.7T

Do we know what mining device hit the block?

No way to know since we dont collect user data and all blocks are generated locally on futurebit devices (unless the block finder like @Block888737 publicly states it).

We are looking into collecting anonymized user data in a future (hashrate, best shares, etc) for a cool leaderboard type data page (and possible rewards program for it). This would obviously be opt in, and would need general consensus if large number of the futurebit community wants it.

Hi guys,

Since there's this recent news about newly found Bitcoin Core vulnerabilities:

"• CVE-2026-117349 (Slow Unbounded Memory Growth via Paused Pre-BIP31 Peers): Affected. A peer can claim to use an older protocol and stay paused, causing message queues to grow unboundedly (up to 2 MB/hour for inbound peers or 5 MB/hour for outbound peers).
• Undo File / Reorg Issue (CVE-2026-117346): Partially affected. While 64-bit Linux systems are largely protected against extreme short reorg corruptions compared to 32-bit or FAT32 setups, node operators should still update.
• End-of-Life Warning: Versions 29.x and older have reached end-of-life and will no longer receive security updates."

should I move my FutureBit Solo Node from the default 28.1 Bitcoin Core version to version 31.0 or not? I solo mine on it, is version 31.0 tested and stable on the Solo Node for mining?

Version 31.0 is fine for Solo mining, but it doesn't address CVE-2026-117346 if that is what you're concerned about. You would need to update to one of the newly released versions: 29.5, 30.4, 31.2, or 32.1. I'm sure Futurebit will push newer versions when they release their next update, but for now you'll need to update manually. You can download the aarch64 binaries from https://bitcoincore.org/bin/ and place them in the appropriate folders on your solo node here: /opt/apolloapi/backend/node/bin

For what it's worth, I've got 29.5 running on my Apollo III and no issues so far. If manually updating your core version doesn't sound fun, I'd stick with what you have until Futurebit provides an update.

Yep, you can just drop in whatever core binary you want in that location and the system will use it as long as you dont switch versions.

2.1.4 is almost out and will have lots of security fixes, miner firmware updates for Apollo III, updated core versions, and depreciating support for knots since that is no longer relevant for our system.

Lots of kernel/OS/ubuntu level updates as well so reflashing image is probably a good idea.

Also working on a massive image update for Apollo BTC/II units that will match the Apollo III subsystem. This will bring many needed fixes for wifi, hdmi etc on those MCU2 boards (driver is finally fixed for all the 5ghz/wpa issues with wifi on these finally after years of neglect (im assuming they finally pointed some LLMs at it upstream).

Apollo OS 2.2 is also in the works, along side a huge overhaul in our build system...this will finally fix all the OTA update issues, and also unify the underlying ubuntu OS with our upstream and low level changes which will finally allow us to do kernel updates/image updates without needing to reflash.

Once those are done we are going to be able to rapidly test and push features at a way faster pace now, and finally start hammering out the long feature lists we have from all you guys!
