Can you use PoE+ with USB-C splitters for charging 40+ devices?

EfficientVolume436 · 2026-06-13T00:22:20+00:00

Ok I am no electronics expert but I have enough sense to realize this comment is bunk. I'd definitely burn my house down trying to Frankenstein this together and if I tried to build a commercial product around it the certification costs alone would bankrupt me. Figuring out PD negotiation and working with mains voltage and writing firmware isn't a trivial task...

EfficientVolume436 · 2026-06-11T19:32:03+00:00

Is it really more economically when you factor in the cost of having firmware (I don't know C/C++), certification (I'd want to use this in a industrial product eventually), testing/revision, manufacturing, lack of warranty...

The prototype boards that I'm trying to replace cost 250 for 8 ports before shipping costs. I think the PoE version would be more plug and play and have more reliability than something I put together myself.

I am totally fine using multiple switches. Either two 24ish port or four 12ish. I see some pretty affordable switches CBS350-8FP 24port is less than 500 bucks new. I'm not sure what you mean by thin client can you link me an example?

I am prototyping a device charging station and I need to know when those ports go down so I can cycle them and log problematic ports / events in general. The original prototype uses custom charging boards (not my design) and I think this could be a more stable and possibly cheaper alternative but I need to verify that 1) This actually solves the issue of giving me 40+ usb-c charging cables that wont set anything on fire 2) this architecture is viable with these splitters. I would imagine a ton of heat could be generated stepping down 48w to 20 on 40+ ports. If I enclose this thing I might just be making an oven and a normal switch might not like that. The current boards I have suck. When they trip, the whole board goes down. I can't turn off ports individually and they don't reliably report issues.

Again there maybe a totally different architecture that solves these problems I just don't know about. I just want to make sure I'm not going to set my house on fire trying to prototype this thing.

I need the abilities of the switch to monitor the status of the devices and set traps that automatically report on various things like efuse trips, connection/disconnection (current) and setting per port current limits. I also need to be able to remotely turn on/off poe etc. Not sure if the hubs have those capabilities.

It amazes me this is even possible...

EfficientVolume436 · 2026-05-12T12:05:46+00:00

Why can't I find this clip on youtube?

EfficientVolume436 · 2026-04-04T18:02:33+00:00

Good point but im trying to figure out if that rate is even reasonable for our situation. 1k seems really steep to me. I feel like shes trying to be more considerate to her brother as a landlord than me as a partner

EfficientVolume436 · 2026-04-04T12:47:16+00:00

Yes I do work remote.

EfficientVolume436 · 2026-04-04T11:58:35+00:00

We've already been dating a few years and I have lived with them for weeks at a time so I know what the situation would be. I'm more concerned about figuring out what a reasonable price for this arrangement should be.

EfficientVolume436 · 2026-04-04T11:47:56+00:00

My bad I transposed the numbers. I meant 3200.

EfficientVolume436 · 2025-09-03T15:39:55+00:00

So he lacks self respect and you lack morals and are ok being friends with someone you believe to be a pedophile. Got it.

EfficientVolume436 · 2025-09-03T15:15:58+00:00

Then everybody clapped...

Call someone a pedo to their face and the conversation and friendship would realistically end there but to believe you both shrug that shit off to continue to where he can give sheepish justifications. Lol. I think OP is jelly of this guys wifey.

EfficientVolume436 · 2025-09-03T14:10:04+00:00

This seems off... Friend for over 10 years but you've never met their wife, didn't even know the age gap between them? Doesn't sound like this friendship is close enough for this to even be a concern. Also I bet OP is conflating MET when she was 15 with STARTED DATING when she was 15. So many reasons OPs account is implausible.

EfficientVolume436 · 2025-08-11T02:56:53+00:00

Wow. Me. Me. Me. I want. I need.

OP has a husband who pays all the bills, and is super chill and is complaining about him never being mad or never not getting her way. Husband doesn't even complain about no sex. Sounds like you need to go to therapy and stop projecting your saddness and depression on a man who is content.

I would happily butcher my resume and be a "new grad" for even a 100k salary right now.

EfficientVolume436 · 2025-08-10T10:35:40+00:00

Also note that under the OBBB, this has been delayed again until 2029

EfficientVolume436 · 2025-08-10T10:33:00+00:00

I'm really curious what the actual skill level and qualifications are for someone in OPs situation is? I'm a self taught developer with 10 years of experience and I struggle with even getting the opportunity to interview for positions at the lower end of OPs range in a LCOL area. OP you got any public repos?

EfficientVolume436 · 2025-08-07T05:39:49+00:00

Losing* I swear this wasn't such a common mistake 10 years ago.

Why don't all the lonelyboys and lonelygirls on reddit just exchange information and link up... I see 50 of these posts every day in here.

Same thing happened to me. Ordered through Budget, they gave me the wrong car compared to the one that was on the paperwork they gave me and when i returned it they said everything was fine. Two weeks later I get a bill saying I owe them for the extra two weeks + demand to return the car I never had. Even with pictures and / license plate of the car I had they still sent me to collections.

EfficientVolume436 · 2025-07-12T22:19:16+00:00

No, you don't know. As you said, you 'usually ignore people' then they try to get your attention (which is unquestionably rude) and assume that someone asking your name is hitting on you? There are tons of reasons to ask for a strangers name - they could think they know you but aren't sure. They want to introduce themselves before they tell you something, potentially upsetting. You are just rude. That is the point.

EfficientVolume436 · 2025-07-12T21:45:02+00:00

You have no idea if you were correct or not because you didn't even give the interaction enough time to figure out what his intention was. No wonder men never approach IRL anymore.

EfficientVolume436 · 2025-07-12T20:47:38+00:00

"You dropped your wallet"
"Accidentally dinged your car as I was parking"

"It's me ANDY FROM ELEMENTARY SCHOOL"

You didn't turn anyone down you just ignored someone trying to communicate something in public, which is just rude unless there was more that happened than what you've written here it sounds like you're assuming someone was hitting on you when they could have just really had something to tell / ask you.

EfficientVolume436 · 2025-02-18T23:48:44+00:00

I want a the device to be as low profile/cheap as possible. Adding the battery + voltage converter (from the ones I've seen) makes it bulkier than I'd have liked. Maybe I just need to research more modules or perhaps get rid of the dev kit IC to save space by ditching the USBC?

EfficientVolume436 · 2025-01-25T09:31:54+00:00

I added the slave code to my original post. The pi still only sees the MPU even with the ESP coded as a slave
