How to Check the Software and Hardware Version of a Raspberry Pi

There are a number of commands which can be used to check the hardware and software versions on a Raspberry Pi.

Version of Debian;

cat /etc/debian_version can be used to see what version of Debian you are running.

pi@raspberrypi ~ $ cat /etc/debian_version
7.8

2015-05-05-raspbian-wheezy

pi@raspberrypi ~ $ cat /etc/debian_version
8.0

2016-02-03-raspbian-jessie

OS Release Notes;

cat /etc/os-release can be used to see OS release notes

pi@raspberrypi ~ $ cat /etc/os-release
PRETTY_NAME=”Raspbian GNU/Linux 7 (wheezy)”
NAME=”Raspbian GNU/Linux”
VERSION_ID=”7″
VERSION=”7 (wheezy)”
ID=raspbian
ID_LIKE=debian
ANSI_COLOR=”1;31″
HOME_URL=”http://www.raspbian.org/”
SUPPORT_URL=”http://www.raspbian.org/RaspbianForums”
BUG_REPORT_URL=”http://www.raspbian.org/RaspbianBugs”

2015-05-05-raspbian-wheezy

pi@raspberrypi ~ $ cat /etc/os-release

BUG_REPORT_URL=”http://www.raspbian.org/RaspbianBugs”

Kernel Version;

uname -a can be used to see what kernel version is running

pi@raspberrypi ~ $ uname -a
Linux raspberrypi 3.18.11-v7+ #781 SMP PREEMPT Tue Apr 21 18:07:59 BST 2015 armv7l GNU/Linux

2015-05-05-raspbian-wheezy

pi@raspberrypi ~ $ uname -a
Linux raspberrypi 4.1.19-v7+ #858 SMP Tue Mar 15 15:56:00 GMT 2016 armv7l GNU/Linux

2016-02-03-raspbian-jessie

To check the hardware version;

cat /proc/cpuinfo can be used to see what hardware you are using. Take note of the revision number in the second last line and then refer to the table below. The output below is from a Pi 2

PiZero 512MB 900092

I thought there were two Pi Zeroes – one with camera socket and one without?

I got my hands on a Zero with the camera socket and I was able to update the table

Now there is also the Zero Wireless available

Pi Zero W:

$ cat /proc/cpuinfo
processor : 0
model name : ARMv6-compatible processor rev 7 (v6l)
BogoMIPS : 697.95
Features : half thumb fastmult vfp edsp java tls

Hi.. Is there any way to check the hardware version of a connected Raspberry Pi Camera Module.. Either v1.x or v2.x?

What about detecting difference between Raspberry Pi 3 Model B and Model B+?

enter command “dmesg | less”. When I do this on my Pi along with lots of other information it says: “Machine model: Raspberry Pi 2 Model B rev 1.1”.

  Alternatively, cat /sys/firmware/devicetree/base/model

My Pi 3 Model B+ is a020d3

Pi model 3 B+

Hardware : BCM2835
Revision : a020d3

There is a complete version table here:
https://elinux.org/RPi_HardwareHistory

Here is a very easy way to see the Raspberry Pi Model and Revision.

dmesg | grep model

FYI, the Pi Zero Rev 1.3 is:

920093(camera connector)

I have a 3B and a 3B+. The last line of /proc/cpuinfo output states that directly as the Model. As in:
Model : Raspberry Pi 3 Model B Plus Rev 1.3
