2.6.1 USB Port by Model

Nowadays, many peripherals such as a keyboard, a mouse, and a camera are all connected to the computer main body through USB.

The Raspberry Pi system also provides a USB port that supports USB 2.0. As Linux already have drivers installed for most peripherals, so you can plug your peripherals into a Raspberry Pi system for immediate use.

2.5.4 3.5mm Audio Jack and Composite Video

The Raspberry Pi offers a 3.5 m audio jack to support stereo. When using HDMI output from Raspberry Pi, audio output can also be transmitted to the HDMI port together with video output, so that external device can play video and audio at once. However, if separate audio output such as a speaker and a headphone is required, audio may be outputted separately through an audio jack.

2.5.3 DSI Display Port

Raspberry Pi supports DSI (Digital Serial Interface) connection to support TFT-LCD display. When connecting the device, you can connect it to the DSI display port protected by a plastic layer over the SD card slot on the top of the printed circuit board.

In addition, in order to use Raspberry Pi with a touch screen without a keyboard or mouse, touch-screen drivers that support 10-finger touch and on-screen keyboards is integrated in the latest version of the Raspbian operating system.

2.4.1 Micro USB Power Supply Port

Raspberry Pi supports Micro USB socket to power the system. Micro USB sockets are a common standard for charging mobile phones and mobile devices.

The power supplied to the system is using a 5.1V DC power supply. How much current is needed in Raspberry Pi depends on the type of Raspberry Pi model and number of peripherals connected to Raspberry Pi.

● System on a Chip(SoC)

Raspberry Pi is a System on a Chip (SoC) type computer. System on a Chip (SoC) refers to the way in which all electronic components required for computer operation are concentrated on one chip. In this method, the CPU, GPU, USB controller, RAM, Northbridge, Southbridge, and other components are compressed and bundled together on one chip without installing separate chips.

2.1 Hardware Configuration of Raspberry Pi

2.1.1 Basic configuration of Raspberry Pi

The hardware of Raspberry Pi has depends on the model, but the basic framework maintains the same structure as before. However, as the popularity of Raspberry Pi has increased recently, and the requirements for higher performance and various functions have been raised, and thus usage area has been expanded, hardware configuration of the latest model is slightly changed to support higher performance and add new functionality.
