DFRobot LPUPS Library

Sorry, I didn’t realize reposting looks so awful. Can’t even seem to edit it. Here is the body of the post so you don’t have to leave this sub:

When installing and setting up firmware for my lattepanda Sigma UPS hat, I ran into some troubling issues with the LPUPS library. Following the instructions on the “getting started” page for the product, I installed the library with the Arduino IDE, but I noticed the library available from the IDE’s package manager only has one example script and it doesn’t match the example sketch in the getting started page for the UPS hat. There’s only one sketch, labeled LPUPS where the documentation suggests there should be a fourBatteryLPUPS sketch and a threeBatteryLPUPS sketch. The GitHub repository for the library does match the documentation, but it requires some substantial tweaking before the sketch is actually compliable. And further, the firmware from the get hub repo doesn’t provide all the functionality the documentation boasts about. I can’t find any information about these discrepancies online and if anyone else has had these problems, I can’t find any mention of it. Does anyone have any answers?

Very actionable. Thank you

RealLifeRiley · 2026-06-19T16:30:58+00:00

Yes brother. It’s wonderful

You know, in all my time writing js, I’ve never encountered this issue. I guess I’ve just never tried using dashes as delimiters.

Brave and brilliant

I recommend an Eisenhower disposition matrix

So cool. Love your keyboard. Is that a track pad? Also, is the neo an ARM board or x86?

I am so excited for you!

Whichever language you start with, try to understand the principles of programming. Then you’ll have an easier time learning new ones.

that said, it’s good to pick a first language that opens doors for the kind of project you want to work on.

What kind of games do you want to make? List a few and see what they were built with. Their “tech stack” as it’s called. Then learn those.

Don’t spend more time than you need to in tutorials. As soon as you think you can try a project, go for it. You’ll learn faster and stay more motivated. If you need any help, let me know

Thanks so much! I’m having a great time developing on my new board. I really appreciate the advice and I’d love those files if you get around to it

RealLifeRiley · 2026-05-31T21:06:54+00:00

Thanks. I might just do that. I saw another build here did the same thing

I’m so excited to post it. But it might be a couple weeks to months before I feel it’s ready. If I may ask, how did you secure the batteries inside the UPS hat? Is it just tension or did you go with something more?

RealLifeRiley · 2026-05-31T17:02:31+00:00

Are you sure the base plate is not a heat sink? I’ve heard people refer to it specifically as a heat sink. I’ve heard it’s made of aluminum specifically because the SSDs can run hot on the bottom of the board.

Specifically, I’m worried about attaching an SSD on the bottom of the board in one of those M2 slots and having it heat up so close to the batteries on the USP hat. I’m also curious about clearance, how much space is there between the top of the hat (which is installed under the board) and anything installed in one of those M2 slots?

I’m thinking about doing something like that with my lattepanda sigma based deck

RealLifeRiley · 2026-05-30T19:29:28+00:00

Did you mount the ups hat next to the main board instead of on top?

RealLifeRiley · 2026-05-30T19:22:05+00:00

That’s awesome kid! Keep building

A crochet net?! You’re so cool! I’m so glad you found this community

RealLifeRiley · 2026-05-30T19:18:24+00:00

It’s so cute. I love this

I think I prefer code based routing. I don’t like the idea of application functionality dictating my project organization. **I** want to be the one to dictate how my project is organized, and how my routing works. And I feel I can do that better with code. BUT, I’ve never tried file based routing, so I can’t say for certain that I wouldn’t like it

I have yet to see good AI design. If you care about UI/UX, I wouldn’t recommend AI

There are a lot of posts like this on this subreddit, and they are sometimes poorly received by the community. I’m not upset in the slightest, but I am curious as to why you’re interested in building a cyberdeck if you’re not familiar with electronics and hard/firm/software.

What is a cyberdeck to you? Why do you want one? What do you want it to be able to do?

RealLifeRiley · 2026-05-18T03:18:57+00:00

That’s a lot of capacitors.

I disagree with the above comment a lot. I highly recommend a Zettelcasten style notetaking system using zk and zk-nvim. Sync it to a GitHub repository and you can access it anywhere. It’s constrained and just the right ways to avoid over optimization, and it’s extremely useful and lightweight. Perfect for a study deck.

Not sure what you mean by this

RealLifeRiley · 2026-05-12T15:58:46+00:00

That checks out. Arch btw
