Normally, all data on a Raspberry Pi is located on the inserted SD card. This has the advantage that you can simply insert a ready-to-use SD card into another Raspberry Pi. If, for example, your Raspberry Pi is damaged, all you have to do is insert the SD card into workable hardware and you can continue.<\/p>\n\n\n\n

But what if you want to clearly identify the hardware used - i.e. the mainboard or the hardware of the Raspberry Pi? A serial number would be very helpful.<\/p>\n\n\n\n

Unfortunately there is no special serial number for the Raspberry Pi hardware. But what can be read is the serial number of the CPU. And since this is permanently soldered to the rest of the hardware and is very difficult or impossible to replace for most people, it can be used as a serial number to identify the Raspberry Pi board.<\/p>\n\n\n\n

How you can read the serial number of your Raspberry Pi or its CPU is described in the following article.<\/p>\n\n\n\n

Safety instructions <\/span><\/h2>\r\n

I know the following notes are always kind of annoying and seem unnecessary. Unfortunately, many people who knew "better" have lost eyes, fingers or other things due to carelessness or injured themselves. Data loss is almost negligible in comparison, but even these can be really annoying. Therefore, please take five minutes to read the safety instructions. Because even the coolest project is not worth injury or other trouble.<\/span>
