To see what version of the Raspberry Pi, all you need to do is run this command:
cat /proc/cpuinfo
or
cat /proc/cmdline | awk -v RS=" " -F= '/boardrev/ { print $2 }'
I have the original Model B.
Processor : ARMv6-compatible processor rev 7 (v6l) BogoMIPS : 697.95 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 : 00000000a1b6318c
If you see, Revision is 0002. Look at the list below to see what you have.

And now a B2
I now have a 3B+
