.SH NAME
raspirev \- Raspberry Pi revision codes
.
.
.SH DESCRIPTION
Each distinct Raspberry Pi model revision has a unique revision code. You can
look up a Raspberry Pi's revision code by running:
.PP
.EX
$ \fBcat /proc/cpuinfo\fR
.EE
.PP
The last three lines show the hardware type, the revision code, and the Pi's
unique serial number. For example:
.PP
.EX
Hardware    : BCM2835
Revision    : a02082
Serial      : 00000000765fc593
.EE
.PP
.B Note:
As of the 4.9 kernel, all Pis report BCM2835, even those with BCM2836, BCM2837
and BCM2711 processors. You should not use this string to detect the processor.
Decode the revision code using the information below, or read
.I /sys/firmware/devicetree/base/model
.
.
.SH OLD-STYLE REVISION CODES
The first set of Raspberry Pi models were given sequential hex revision codes
from 0002 to 0015:

.SH NEW-STYLE REVISION CODES
With the launch of the Raspberry Pi 2, new-style revision codes were
introduced. Rather than being sequential, each bit of the hex code represents a
piece of information about the revision:
