Revisions

The raspberry pi now comes in a number revisions and versions. Its important to know your revision and version because the GPIO ports are configured differently. To find out your pi revision type:

		
cat /proc/cpuinfo

this will then display all the information about your pi, like the following

		
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

Now look your Revision number up in the table below

GPIO Versions

The GPIO pins are configured differently for different Pi Revisions, currently there are 3 GPIO pin outs:

Raspberry Pi Version 1

Early Pi – without mounting holes

gpio-pinout

Raspberry Pi Version 2

Most Pi’s before the A+, B+ – with mounting holes

gpio-pinout-rev2


Raspberry Pi Version B+

including A+, B+ and the new Pi 2

GPIO B Plus

GPIO B+
