The latest version is now over a year old, so an update is long overdue. The Raspberry Pi foundation has just announced the next generation Pi, which represents a significant upgrade and now offers makers the choice of 1, 2 and 4 GB flavors of memory.

The first product launch since the Raspberry Pi Store was opened in Cambridge, UK, the Pi 4 B comes with a more powerful – and more modern – processor than the boards before it, thanks to a switch from 40 nm silicon to 28 nm. That shapes up to 1.5 GHz ARM Cortex-A72 quad-core brains which promise a performance hike of between two and four times over the Pi 3 B+.

Up to 4 GB of RAM is available, but the move to LPDDR4 also means more bandwidth. USB connectivity has been brought up to date too. The micro-B power port has been sacrificed to USB-C, which supports an additional 500 mA of current. Elsewhere, makers also get two USB 3.0 and two USB 2.0 ports.
