In order to find out what hardware revision you have you can run the following command at the command prompt or via a terminal window :

 cat /proc/cpuinfo

This will give you a text output something like this :

Processor       : ARMv6-compatible processor rev 7 (v6l)
BogoMIPS        : 847.05
Features        : swp half thumb fastmult vfp edsp java tls
CPU implementer : 0x41
CPU architecture: 7
CPU variant     : 0x0
CPU part        : 0xb76
CPU revision    : 7
Hardware        : BCM2708
Revision        : 0002
Serial          : 000000000abc0ab1

In this example I’ve got a PCB with a Revision code of 0002. That is a plain old “Model B Revision 1.0”.

NOTE : The Revision number given in cpuinfo file is the hardware revision number. This is not the same as the Raspberry Pi Revision. In this example I have a Model B Revision 1.0 with a hardware revision code of 0002.

Model Information

With the latest version of Raspbian you can also retrieve the Pi model as a string by using :

cat /proc/device-tree/model

This will output the model information. For example :

Raspberry Pi 3 Model B Rev 1.2
