Raspberry Pi is NOT a credit card sized computer

Raspberry Pi... A small rather cheap and rather powerful computer. No problems with that.

What about marketing?

You see, it is marketed as being a credit card sized computer. Well, let's see...

A credit card size is 85.60 × 53.98 mm and Raspberry Pi size is... 85.60 × 53.98 mm


Yet a credit card is 0.76 millimeters thick (there's an international standard for that) but Raspberry Pi is 17 millimeters thick.

Now grab a calculator and ensure that 17 millimeters is something like 22,37 times more than credit card permitted thickness. This kind of means that you need at least 22 credit cards to occupy the volume Raspberry Pi occupies (and to make any credit counselor seriously worried).

Don't believe that? Okay, follow this plan: get Raspberry Pi, get to the nearest ATM and try to insert Raspberry Pi into ATM card slot.


It's not credit card sized, it's size of a cigarettes pack, but that's not so good for marketing.

This also explains why "electric imp" module being packed into an SD card is so cool. Although you likely won't really need to use it in the form of an SD card you can be damn sure that it fits into SD card dimensions and you don't need 7,98 times more height than an SD card would occupy.
