I have never had anything break on Debian.

I use Arch btw.

set up your own openproject docker instance and plan your next event

try BAR - beyond all reason

cat is build better. cat can stand good.

in australia even the internet is trying to kill you

square feet must look funny

i like those triple supplies from rigol. its much like the siglent you posted, but the 3rd channel is not fixed. its also fairly easy to script it with python. dp800 series.

404 😕

exactly. why is the board damaged? looks like water ingress

yes i think so, but u would have to make sure the solder will rise through the through-hole as mich as possible. maybe u can try to find the faulty pin with wiggling them separately

pressfit connections usually are very reliable. if there is a poor connection i would presume that the barrel of the via is broken and a new pressfit connector will not help. maybe putting solder in would help. did you already test for poor connections?

ah well, then it doesn’t work proper with 5v unfortunately

usually fans have a min start voltage. u can try if your fan starts at 5v and if the resulting RPM is ok for you, just solder it without any resistor on USB

i would probably do some circuit with a TL431 and FETs, but this also drains some small amount of battery current.

i assume its measured under laboratory conditions, so it seems ok to me. TCXO, OCXO should usually be operated within their operating voltage range. depends on type. usually i would assume 1.8-3.3v, but who knows without datasheet?

it could be worth a try to contact diodes and ask which components use or have used in the past V-QFN2030-12 (Type HE) package

looks very similar to that: https://www.ti.com/product/TPS566235

diodes uses packages like this one: https://www.diodes.com/assets/Package-Files/V-QFN2030-12-Type-HE.pdf but cant find FMM marking there …

unfortunately i neither could find anything. richtek has some weird packages like this:

or like this:

so i poked around their homepage. but could not find anything with that pinning. also FMM marking is not in their marking reference :(

How many pins does it have? I can’t see it properly in the image. Is it 4, 8 or 12 pins?
