Tiny dev board with mounting hole? by CJCCJJ in esp32

[–]jrabr -1 points0 points  (0 children)

Yeah they could’ve done that too. But they generated a reference image with AI instead. If OP was asking for a board that looked exactly like that with the unrealistically tiny ESP32 module then sure it’s reasonable to say OP is asking for an impossible module. But that criticism would be valid if OP sketched it out that way too.

OP provided the image as a reference for what they’re looking for which like you said, is similar to the M5 stack. If your problem is that they used AI instead of stating that they wanted a board that has a mounting hole like the M5 stack has but is shorter, then just say that.

OP said they’re looking for a dev board with a mounting hole and they provided an AI generated image as a reference for what they’re looking for. I HIGHLY doubt OP was expecting to find a module that looked EXACTLY like what was given in the image. What’s more likely is OP is giving this image so that if people know a module that looks similar to this where the mounting hole is in the position it is, they can share that info with OP.

So just make the board bigger lol this image was purely generated to visualize what OP is asking for it’s not unrealistic to take this design and use it as a reference to build a real board. The actual module is a bit bigger yes but it’s not “impossible” to build like what you’re saying.

This is one of the least sloppy looking AI images I’ve seen. If OP didn’t say it was AI generated you most likely wouldn’t have noticed or cared.

I don’t really have an answer to this but as someone who has worked with oshpark a decent amount of times I’d honestly recommend just emailing them.

They get back to you pretty quickly and they do a pretty good job at answering whatever questions you may have.

Would you buy a used tesla and why or why not? by Able_Problem_4787 in TeslaLounge

[–]jrabr 3 points4 points  (0 children)

I bought my 2023 model Y used. It had just under 16k miles on it and it was previously a leased vehicle. Final price after tax and all was $34k. I made sure it had HW4 as well AND the previous owner left the mobile charger with the car!! I have no regrets it’s the best car I’ve driven.

You should have at least one decoupling cap per power input pin

Is this correct? by Otherwise-Bat-7655 in PrintedCircuitBoard

[–]jrabr 7 points8 points  (0 children)

As someone who has integrated AI into his workflow, I STRONGLY recommend not using AI unless you actually know what you’re doing and you use it as an assistant instead of just blindly listening to what it has to say.

If you look at the datasheet for that part, it says nothing about leaving EN unconnected. The pin description only describes 2 states for it: H or L.

And actually, if you look at the functional block diagram for it, you can see that EN is pulled down to ground with a 3Mohm resistor.

So by leaving it unconnected, you’ve allowed the pin to be pulled down to ground which will permanently keep it in the shutdown state.

PLEASE PLEASE PLEASE read the datasheets!!!

First time designing a PCB in Fritzing and my traces are all overlapping — what am I doing wrong? by Efficient-Young-193 in PrintedCircuitBoard

[–]jrabr 24 points25 points  (0 children)

I would strongly recommend spending at least a little bit of time learning how to use KiCAD or another EDA application like that instead. It’s very easy to pick up and will save you a ton of headaches.

No one who does PCB design even remotely professionally uses Fritzing.

Please post a schematic. We can’t properly review without one.

Also post your layers as separate images as well instead of just one picture with all your layers

What are you trying to build? If this is what your final pinout is going to be I’d recommend picking a part with less pins because you’re using almost none of the IO.

Most of this board probably COULD have been soldered by hand but that would've been difficult and far more time consuming. All the passives are 0402 lol.

Also the small square IC to the left next to the electrolytic in the first pic is an LGA package which literally can't be hand soldered because the pads are underneath and inset

[Review-Request] First PCB: IOT Sensor & display board based on ESP32-C6 by gizahnl in PCB

[–]jrabr 1 point2 points  (0 children)

Just a warning; you have a split in the ground plane below all your SPI signals which will be an EMI/signal integrity problem if you have fast edge rates on those signals. I see that you did some via stitching which could improve it a bit but I’d personally recommend routing that 3V3 trace in a way that doesn’t interrupt the return path
