Handy new post from The Pi Hut.
What’s so special about Raspberry Pi?
It’s a question that I’m often asked and the answer is usually the same. The GPIO pins of course! Those little stabby pins along the top of the Pi that let you connect buttons, buzzers, sensors and HATs.
On the first two models of Raspberry Pi, there were only 26 pins, but it quickly became apparent that more is better and so for every model since the B+ in July 2014, there have been 40 GPIO pins on the Raspberry Pi A and B models. On the Raspberry Pi Zero, there are still 40 pins that you can use, but they are ‘headerless’ meaning that you can either solder directly onto the board in place of the pins, or you can solder your own header on (which is not as tricky as it sounds, and can be great fun).
