Raspberry Pi
The Raspberry Pi is a series of small single-board computers developed by the Raspberry Pi Foundation

Raspberry Pi 4

Features

The speed and performance of the new Raspberry Pi 4 is a step up from earlier models. The fanless, energy-efficient Raspberry Pi runs silently and uses far less power than other computers. Raspberry Pi 4 comes with Gigabit Ethernet, along with onboard wireless networking and Bluetooth. The new Raspberry Pi 4 has upgraded USB capacity: along with two USB 2 ports there are two USB 3 ports, which can transfer data up to ten times faster. The Raspberry PI 4 has support for up to two 4K displays through its two Micro HDMI Ports.
