Unfortunately, the RPi conglomerate does not publish full schematics, or a parts list. Consequently, unless the part you are interested in is covered on their partial schematics, you will have to measure the resistor value with an ohmmeter. The difficulty with this of course is two-fold: The resistor must be removed from the circuit to get a dependable ...

I dont know why, but when I use the raspberry pi4, icm with external powered USB HDD, the whole drive got corrupted, including the filesystem. I had to format (quick format) and do multiple disk check under Ubuntu desktop to repair the HDD. This was using ext4 mount. The same happend when I format the drive as NTFS and mount using ntfs-3g. All the rest is ...

See What OS version is installed cat /etc/rpi-issue | grep reference will show original image. AFAIK there is no simple way to work out which Pi but there is NOTHING which would differ based on model if they are fully updated. sudo tune2fs -l $(mount -v | awk '/ on \/ / {print $1}') | grep created will show the date the filesystem was created, which for most ...

You are out of luck. It can't be done with a Pi4. See my answer in the linked question - the I²C bus is used for other things on Pi3 & Pi4 (I suspect controlled by Video Core). These pins can be used for some purposes; I have used for UART.

There are no schematics published for the Raspberry Pi. Only reduced schematics are available, which show connectors and parts of the power distribution circuit. You won't find that resistor in there. From the looks of it this could be a pull-up / pull-down of some sort. If I had to do this without any schematic, I would solder a 100 kOhm resistor and see if ...

The simplest of-the-shelf device to do this would probably be a low-resistance meter, using 4-terminal sensing. You could probably create your own version, but the design would be quite tricky, as the actual resistance value will be really low. Would it be cheating to use the metal plate as a core in an inductor? I'd guess that your materials show very ...

See Pi4 Boot Problems Sticky There is nothing that matches, so maybe you need to recount. The documentation may be slightly out of date.
