The table below gives the speed specifications of various Raspberry Pi models and generations focusing on the version’s weight, General Purpose Input/Output (GPIO), central processing unit (CPU) speed, Cores and Random-access memory (RAM) − Raspberry Pi Version The table below gives the speed specifications of various Raspberry Pi models and generations focusing on the version’s release date, form factor and dimensions − Raspberry Pi Version Raspberry Pi Zero models, which come with or without GPIO (general-purpose input output) headers installed, are the most compact of all the Raspberry Pi boards types. On the other hand, the Raspberry Pi A models have a smaller and more compact footprint and hence, these models have the reduced connectivity options. Generation 1 Raspberry Pi had the following four options −Īmong these models, the Raspberry Pi B models are the original credit-card sized format. In 2012, the company launched the Raspberry Pi and the current generations of regular Raspberry Pi boards are Zero, 1, 2, 3, and 4. It is one of the best-selling British computers and most of the boards are made in the Sony factory in Pencoed, Wales. But apart from that, it is used by thousands of people of all ages who want to take their first step in computer science. It is widely used to make gaming devices, fitness gadgets, weather stations, and much more. Earlier, the Raspberry Pi was used to teach basic computer science in schools but later, because of its low cost and open design, the model became far more popular than anticipated. Raspberry Pi, developed by Raspberry Pi Foundation in association with Broadcom, is a series of small single-board computers and perhaps the most inspiring computer available today.įrom the moment you see the shiny green circuit board of Raspberry Pi, it invites you to tinker with it, play with it, start programming, and create your own software with it.
