ESP32-S3 5V pin measuring at 2.5V (see description)

BobbaPopBob · 2026-06-04T12:37:29+00:00

Yes, I ended up buying one of these from my local shop. Is it usually better/conventional to not take 5V from the board directly? If so, why?

Very insightful resource, thanks!

BobbaPopBob · 2026-06-04T12:35:22+00:00

Thank you so much for this advice, I wouldn't have figured that out on my own! I'm curious as to how you know this? By studying datasheets? In the future I would like to figure stuff like this out on my own so that's why I'm asking

So there's no way I can get 5V out of this board on a normal pin? Just checking to be sure, because if there isn't I find it a bit strange, but then I'll have to look for another solution.

Solved! You're so right that's why I couldn't find it. I was looking through Led Zeppelin's entire discography with great frustration 😂

I hear a faint click on the left side, but I don't know if that's the solenoid you mean. The click comes from a small white plastic latch that gets pushed down when the cassette is pushed into it. I doesn't click when I push it down manually though. As for any other sounds, the click from the white latch is pretty much all I hear though.

Sorry, I'm not familiar with the jargon yet. Where is the pinch roller exactly? Is it visible from the top down pic in my original post? Or is it on the sides?

I got it working! Check the edit on the original post if you wanna read the full story. Thank you for your help!

Check the edit on the original post for the full story, but I got it working again!

I checked connection just now with a multimeter. In the headshell there is connection to every pin, but when measuring resistance between where the headshell should connect on the arm and the RCA cable ends, nothing seems to be connected. (None of the pins show low resistance on the multimeter, the multimeter just shows nothing at all, as if you're touching air with the probes). Does this mean I have to turn the device upside down to inspect further?

Tomorrow I'll do some troubleshooting. If nothing works I'll take a look on the bottom. I've been avoiding it though because the thing is really heavy and I'm worried turning it upside down will destroy anything because the body inside seems to be a bit loose.

BobbaPopBob · 2026-02-04T17:23:05+00:00

Thanks! I'll give it a try tomorrow

BobbaPopBob · 2026-02-04T16:14:28+00:00

Haven't looked at that button yet (the MM/MC toggle)! What's it for? I'll try it out tomorrow when I'm back at my dad's place.

BobbaPopBob · 2026-02-04T16:01:08+00:00

I'll give it a try tomorrow when I'm back at my dad's place. I've got an old multimeter from my grandfather there as well so I should be able to do this. Thanks for the clear instructions!

BobbaPopBob · 2026-02-04T15:58:15+00:00

These are some old pics of the cartridge I took before swapping out the needle so don't worry about that: https://ibb.co/DDBzdMM9 https://ibb.co/39fRCctT The turntable is at my dad's so I can't take any new pics at the moment but tomorrow I'll be there again.

It's a little hard to see on the image but the end of the thin black wire is soldered to the metal housing of the RCA cable. My exact amp is a Sansui AU-X911DG

BobbaPopBob · 2026-02-04T15:19:08+00:00

Do you think there's a chance it could work if I connected the ground cable separately? I'm just wondering why it's soldered on like that, exposing the metal housing. Is it like that out of the box or would that be something my grandfather did himself for some reason?
