@cragen Loch Today I had the time to try out your suggestions. I used your suggested https://www.tindie.com/products/jeremycook/ez-fan2-tiny-raspberry-pi-fan-controller/ When using the default GP...

X735 Power management board+ X862 + X857-C3    survivor io X708 UPS + X862 + X857-C3 I got it. Thanks for your sharing.

The NASPi version that is now available does not allow the function of automatically turning on the device; however, the AUTO ON function will be included in the subsequent version.  You can c...

Could you perhaps try formatting the solid-state drive (SSD) so that we may test it once more? https://wiki.geekworm.com/File:Tutorial_Initalize_New_SSD.pdf google

I think X708 ups are not compatible with X750 ups in any way.  

dmesg log also has such messages on each attempt to read from ssd: "nvme I/O 960 (I/O Cmd) QID 3 timeout, aborting"

Hi! I've installed X1002 with NVMe (non-Phison chipset). Then I booted to linux OS and put dtparam=pciex1 to config.txt - it let the SSD drive to become visible. But it operates VERY slow! It makes...

I found my problem. My SSD has Phison controller. As noted in https://geekworm.com/products/x1001 it's not compitable. 

Update:Imaged an USB drive.  Without the SSD plugged into the Pi it boots fine with the USB drive. With the SSD inserted in the hat it won't start (green light, full fans & no HDMI output)...

I tried all suggestions above, but my Pi5 won't boot with the X1001 hat. The blue light is on, but nothing happens (Pi5 light is green, screen show no signal and fans are noisy). The Pi5 also does ...

@Ivan Podogov If your DOS partition was obtained by flashing the Raspberry Pi OS, it should be fine, but many users are using OLD SSDs, which will have old OS on them, such as windows 10 or other O...

We've found customer feedback that they don't recognize SSDs, the firmware & configuration are fine, and there's no problem with the power supply. But just not recognized. The final solution i...

Based on the schematics shown, I think the fan contoller you found would work.  It's a very similar design to the one I used (perhaps better). Connect the fan to JP2 pins 1 & 2 (minding t...

Thank you for the excellent solution, I just ordered this from Tindie. Unfortunately, the shipping for Tindie products to Europe costs more than the fan controller itself. In Germany, I only foun...

Note, the kvmd-fan code to fix the PWM mode is on the "pwm_mode" branch of the forked repository linked above.

The 30mm fan that comes with the A3 kit is only a two wire fan, and is connected directly to 5V power.  It runs at full speed all the time.  However, with a little mod, you can get a PWM ...

You are absolutely right, I recently saw such a case, if I see it again, then I will share the resource

If you have documentation or libraries provided by the x728 UPS manufacturer to interact with it via Python, you should refer to that documentation or official resources for information on how to g...
