Raspberry Pi and Operating Systems

Raspberry Pi OS (formerly Raspbian) is a Debian-based operating system optimized for the Raspberry Pi.
Fedora-based operating system optimized for Raspberry Pi is known as Fedora IoT.

Hardware Components and Functions

The GPU (Graphics Processing Unit) is responsible for speeding up image calculations on the Raspberry Pi.
The HDMI port connects the Raspberry Pi to displays, allowing video and audio output.
The CPU (Central Processing Unit) is deemed the 'brain' of the Raspberry Pi.

Connectivity and I/O

GPIO (General Purpose Input/Output) pins are used for interfacing with various hardware components and sensors.
USB ports facilitate the connection of peripherals such as keyboards, mice, and storage devices.
The Ethernet port ensures wired internet access on the Raspberry Pi.

Indicators and LEDs

The PWR (Red) LED indicates that the Raspberry Pi is receiving power.
An LED indicates SD card activity, flashing to show that the SD card is in use.
The 100 (Orange) LED behaves by flashing during an active Ethernet connection, showing network activity.

IoT Functionality

In the Internet of Things (IoT), a 'Thing' can be any object that can be identified and managed via the internet.
Actuators provide functionality by controlling physical processes in IoT devices.
Communication modules in IoT devices manage data exchange and connectivity.

Serial Interfaces and Pin Configurations

The serial interface on a Raspberry Pi allows for communication with other devices and data transmission.
The Raspberry Pi has dedicated pins for the SPI (Serial Peripheral Interface), facilitating high-speed communication.
GPIO pins operate at a voltage level of 3.3V on the Raspberry Pi.

Additional Information

Identifying a non-pin configuration on the Raspberry Pi involves recognizing configurations that do not exist in its setup.
