Famous in part for its small size, the Raspberry Pi line of inexpensive computers is famously no bigger than a deck of cards, and the Raspberry Pi 4 Model B measures just 3.4 x 2.2 x 0.4 inches.

The Raspberry Pi 4 B offers 802.11ac Wi-Fi, the same as the Raspberry Pi 3 B+, but sports Bluetooth 5.0, compared to Bluetooth 4.2 on the Raspberry Pi 3 Model B+.

An introduction to the Raspberry Pi 4 Model B computer, from how to set it up, to what you can do with it. Written by Nick Heath, Contributor July 2, 2019 at 8:51 a.m. PT WHAT IS THE RASPBERRY PI 4?

The new model is built around a Broadcom BCM2711 SoC, which, with four 1.5GHz Cortex A72 CPU cores, should be a big upgrade over the quad-core Cortex A53 CPU in the Raspberry Pi 3.

While the Raspberry Pi 4 and Raspberry Pi 3 Model B+ look almost identical (they measure 85 mm x 56 mm, and the board layout is similar), their input/output ports are anything but.

The Raspberry Pi 4 Model B Computer offers significant enhancements in processor speed, multimedia performance, memory and connectivity that will make it attractive to general desktop computer ...

The Raspberry Pi 4, on the other hand, is the predecessor of the Raspberry Pi 5. It was released in 2019, just a few months before the world shut down due to COVID-19.
