PENTA SATA HAT external 12V high pitch sound

#1

I’m using a Penta SATA hat for Raspberry pi 5. I can’t get it to work with an external power supply and I’m using the official usb-c type power supply (it turns out to be enough for two SSDs).

Since I want to use all four SSDs, I bought a 12V/6A power supply and when I connect it to the Raspberry Pi 5 (still two SSDs), it doesn’t want to boot. As soon as I connect the power to the HAT, a high-pitched sound is heard.

I also tried another power supply which is specified as 12V/4A with one SSD. The same high-pitched sound. It doesn’t sound good.

Does anyone have such experiences?

I repeat, HAT works with the official usb-c power supply.

If it means something, PENTA SATA HAT was purchased from Radax AliExpress.

From where it coming? power supply or hat?

Can You take a photo of this setup and power supply?

No :slight_smile:

Thank you @dominik for respond.

To photograph setup I have connected PI5 to external power supply and now booted! Fan started spining. Very strange, system is stable. This is good news but I am concerned about high pitch noise.

Noise is from HAT power part. Sounds like coil resonating but not sure.

This is photo of Power supply.
Didnt test power supply on load, messured voltage is 12.3V.

This is sound recored with smarthpone.

Sorry, can post max. two links. I can send picture of setup in next post.

This is video of setup

Now as system is running I am able to monitor voltages.

This is output of vcgencmd command.

Have You any chance to test it with different power adapter?
For sure it should not give any additional noise and high pitches, are You sure sound is coming from hat and not pi itself?

#6

Found ATX power supply (500W) and conected to HAT using molex connector. PI 5 is booting but high pitch noise remains.

My setup is behind TV and five meters away squeaking sound can be heard.

High pitch noise is synced with activiy LED. As if some SMD part is resonating on power demand.

I am not 100% sure that noise comes from HAT but fact is that sound stops when HAT is powered with USB type C.

Did seller sent me damaged board, I don’t know but I have bad expirience with this HAT.

Nead more suggestions to detect problem. Thanks in advance.

More people were complaining about such issue, like here:

or here:

Second one was already dead, but still produced it’s noise. I don’t know if it came back to radxa and was diagnosed or not. Ask @setq for details.

Try to power HAT without board, check if noise is still coming from it,
Do You have any thermal pad to cover element near power jack? You may try to find if this one cause issue.

You may try to replace Your HAT, obviously not everyone has this issue,
Maybe problem will not be noticeable under some heat pad, heatsink and in case, original one is really thick and probably will solve the problem.

@dominik thank you for research. Reading posts you sent and sound like same issue.

I have contacted seller and opened dispute.
