It uses the same quad-core 1.4GHz Broadcom processor as the high-end Model B+. It also has the same support for Bluetooth 4.2 as well as 2.4GHz and 5GHz Wi-Fi. But there’s no longer an Ethernet port (you have to use Wi-Fi), there’s only 512MB of RAM instead of 1GB, and it drops to just one USB 2.0 port instead of four. It’s also a smaller board measuring just 65-by-56mm. This new model offers more power, connectivity, and expandability.
Eben Upton, chief executive of Raspberry Pi Trading, explains that “whatever we do next will of necessity be less of an evolution, because it will need new core silicon, on a new process node, with new memory technology. So 3A+ is about closing things out in style, answering one of our most frequent customer requests, and clearing the decks so we can start to think seriously about what comes next.” The Raspberry Pi Foundation is a charitable organization registered with the Charity Commission for England and Wales. In 2016, The Foundation moved its headquarters to Station Road, Cambridge, being supported by the University of Cambridge Computer Laboratory and Broadcom. Its aim is to “promote the study of computer science and related topics, especially at school level, and to put the fun back into learning computing.” A tiny and affordable computer is their goal.
