Peripherals (including keyboards, mice and cases) are not included with the Raspberry Pi.
I have got earlier model of Raspberry 2 B+,purchased at around 2014 from Amazon.These boards are approximately are credit-card sized. Improved A+ and B+ models were released a year later (around 2015+).Raspberry Pi Zero with smaller size and reduced input/output (I/O) and general-purpose input/output (GPIO) capabilities was released in November 2015.
