The Raspberry Pi 4 Model B line is a desktop computer in a package the size of a credit card. All you need to do is plug in a monitor, keyboard, mouse and load the latest Raspbian image onto a MicroSD Card and you have a full desktop computer solution. Projects like Tensorflow, PiHole, Minecraft, and Kodi make it an excellent tool for a multitude of uses.

The RPi4 retains a lot of the features of the RPi3 B+ including the pin-out for the 40 pin header. Wireless is still available on the 4 in the form of dual-band 2.4/5.0 GHz WiFi and Bluetooth 5.0. A new feature on the 4 is the inclusion of a USB Type-C connector for power delivery replacing the Mini-B connector.
