Raspberry Pi

Raspberry Pi is a small, extremely inexpensive single- board computer. It is about the size of an ID1 card and is preferably used in the hobby area for experimenting and for applications in the Internet of Things( IoT). Raspberry Pi computers, developed by the Raspberry Pi Foundation, come in various versions.

All versions contain a system-on- chip( SoC) with a quad-core processor as well as various interfaces for USB, HDMI, Ethernet, audio, video, GPIO, a display serial interface( DSI) and a camera serial interface( CSI). The memory is provided by an SD card. Depending on the version, a standard SD card or a microSD card is used. Current versions have WLAN.

Raspberry Pi has a customized Linux with graphical user interface as operating system. For IoT applications, Windows 10 is also used in a special variant. Mass storage devices can be connected as external solid-state drives( SSD) or as USB sticks to the USB interface. Power is supplied via a micro-USB interface with a power of 2.5 W.

The Raspberry Pi single-board computer is not designed for performance, but as a simple, flexible platform for applications in education, industrial or experimental use. It offers connectivity for a keyboard and mouse, as well as a display, digital camera, an RJ45 connector for Ethernet, an RCA connector for video, and an audio connector for headphones.

The Raspberry Pi 4 model has a RAM with 8 GB and a maximum clock speed of 1.5 GHz. In addition, Pi 4 has two micro HDMI ports, which enables operation of two 4K displays. A quad-core processor from Broadcom serves as the processor. Besides that, there are two USB 3.0 interfaces in addition to the USB 2.0 ones.

Raspberry Pi Zero

#2 Raspberry Pi Zero includes other members of the Raspberry Pi family. First single-board computer of this Raspberry family was Raspberry Pi Zero W, which is followed by Raspberry Pi Zero 2 W. This computer targets IoT projects and wireless networks. Whose central component is the quad-core 64-bit ARM Cortex processor running at 1 GHz. In addition, the board also includes the VideoCore IVgraphics processor, a power supply with micro USB and a camera port. There are connectivity options for WLAN, Bluetooth or Bluetooth Low Energy( BLE) and mini-HDMI.
