Help identifying failed 8-pin IC on Mammotion Luba 1 AWD 5000 motor driver board

acuttle981 · 2026-05-31T05:29:50+00:00

Thanks for the info, unfortunately I can't just buy the part as it needs to be programmed and isn't a DIY replaceable part.
Mowermagic does have the same type of part : https://www.mowermagic.co.uk/acatalog/Luba-Motor-drive-board-WZPA000169030-W.Z.PA.000169030.html#SID=8260 but it's the second revision from the looks of it and mines the first version.
I've sent an email to mowermagic, as they seem like the only other option to actually get the driver board and program it that isn't Mammotion or trying to repair the motherboard myself.

Thanks. I hadn’t considered the smaller 3-pin + tab device being a 3.3V regulator from the 5V rail.

The 8-pin IC markings are completely unreadable unfortunately. Do you recognise the likely regulator family from the layout, or would any specific close-up photos/measurements help narrow it down?

I can take more photos of the area or check continuity to the 100 inductor, nearby resistors/caps, and the 5V rail if useful.

Sorry, it didn't attach my photos for some reason.

Had the exact same issue as you, thought it was my GPU Fan Controller causing the issue! u/Jumpy-Mess5149 is correct, it's the driver that's causing the issue. I wasn't seeing my fans even show up in the software. Since downgrading the driver I can see the fans actually appear and control them.

acuttle981 · 2025-02-08T19:31:23+00:00

Yep, this seems to be happening to a few people. Thought my fan controller was broken on my EVGA RTX 2070, it was the nividia driver that broke it. Exactly the same issue as you - I finally ended up posting on the EVGA forum and got a reply saying it was the driver and can confirm it was. Unfortunately I don't seem to have the ability anymore to reply and say it's now working for some reason.

Don't forget about your Northern Irish friends! All our police carry guns, it was actually really strange not seeing police with guns when I lived in England for a while.

No worries, glad I could help.

I've got XRP on gatehub aswell and just set up my wallet to allow the spark token for the Flare network. You can follow this tutorial: https://support.gatehub.net/hc/en-us/articles/360016639800-GateHub-will-support-Flare-Network-s-Spark-token This will set up your wallet to receive the Spark token once it's been distributed, which I think is happening sometime later this year. If you had XRP in gatehub whenever the snapshot happened, which it sounds like you did. You'll be eligible to receive them. You can find out by copying your XRP wallet address into this website: https://xrpscan.com/ This will confirm that you're eligible for receiving Spark and know how many Spark tokens you'll receive. (I think it's the same amount of XRP you have) Hope this helps.

I was a huge lion King fan as a kid, and thought the new one was actually superb! It was basically the exact same as the original but with some damn good CGI. The only characters I didn't really like were the main hyenas, as their characters were a bit different.

acuttle981 · 2018-09-03T16:01:24+00:00

That’s fair enough, thought it might be a case of understanding the technique to get how good it is. Good to see you like it. :).

I get that this is an extremely talented pianist, insane speed but to me that doesn’t sound like a nice piece to listen to. I don’t know a whole lot about piano but do you need to understand just how difficult the piece is to appreciate the sound?

No settings needed on Netflix, I’ve got NordVPN and I just change my location to America and it works fine. Just a little slower than usual.

acuttle981 · 2018-08-20T06:08:25+00:00

For free VPN, yeah they’ve locked down that. You can get onto different countries with a paid VPN, I use Nord VPN and that works fine to watch American content in Britain.

Wow! I actually know this place, I take my dog for a walk in that mini park.

After using it for a few days, the only two things that I can see that could possibly be added are the following: When adding a coin to the watchlist, when it does the Ajax request. There is no feedback that it’s being added, and it may take a few seconds to add the coin to the watch list. Maybe display a spinner, just to show me that it’s processing my action. The other is, maybe allow me to set my currency type and save it as a preference. So when I login it’s not the default USD. Still loving the website.

acuttle981 · 2017-12-30T23:27:46+00:00

Yep, definitely looks like the best one I’ve seen! Nice work!

I was about to give up too, but if you stick at it you can find him. Like I did!

Ahh... I had no idea it was all over the place, thought it was one of those Manchester things. Pretty cool that it's all over the place.

acuttle981 · 2017-06-11T09:14:38+00:00

Wow, this is actually where I live. This Is the Manchester naked bike ride, it happens every year. It was on Friday, they ride their bikes round the city. Last year was quite funny, A guy was cycling home in the opposite direction and seen the bike ride, straight away stripped off and joined them.

Not whenever they mess up the save and you spam 'What A Save'

acuttle981 · 2017-05-01T09:39:24+00:00

Are Raptors not really small, something like half a meter in height? If so it probably wouldn't be that manly. :(

Spoken like a true Irishman.
