The Raspberry Pi is an innovative computer that’s small enough to fit in your hand but powerful enough to be a full fledged computer. It only costs about 35 dollars and is designed to teach young people about computers. This computer runs a free Linux software from an SD card just like ones in your camera or cellphone.
This relates to engineering because people came together and invented this computer. It’s as small as a credit card but has all of the functions a computer does. All you need to do is plug in an HDMI cable and plug it into a monitor and then you can use it.
