Raspberry Pi
Raspberry Pi is a series of low-cost, single-board computers produced and developed by the UK-based Raspberry Pi Foundation. These devices are designed to enable users to learn programming, develop electronic projects, and run various applications. Raspberry Pi is often abbreviated as "RPi."
Raspberry Pi boards come in different models, each with varying technical specifications. Generally, these boards feature an ARM-based processor. Processor speed and capacity may vary depending on the models. Additionally, different amounts of memory are available. More memory can facilitate the execution of complex projects.
The device includes various connectivity ports such as USB ports, Ethernet connection, HDMI output, and more. It also features General Purpose Input/Output (GPIO) pins, allowing you to connect external devices like sensors, motors, and LEDs to Raspberry Pi, enabling the development of various electronic projects.
Typically, the operating system and data are loaded onto a microSD card. Newer models may offer built-in storage options.
There are various operating systems available for Raspberry Pi, with the most commonly used one being known as Raspbian (now Raspberry Pi OS).
The device is typically powered via a micro USB or USB-C connection.
The Raspberry Pi Camera Module is a hardware component that can be attached to the Raspberry Pi to add image and video capture capabilities. This module typically consists of a sensor, lens, and an interface board. Raspberry Pi Camera Modules are used by attaching them to the GPIO (General Purpose Input/Output) pins of the Raspberry Pi.
This module is a popular choice, especially for users who want to capture images and record videos in projects. It offers different resolution and feature options that can be used for various applications and projects. Resolution options may vary depending on the model, allowing you to capture media of the desired quality.
What Is a Raspberry Pi Shield?
A Raspberry Pi Shield is a type of external hardware module used to expand the capabilities of the Raspberry Pi. These boards, often referred to as "shields" in other platforms, are known as "HAT" (Hardware Attached on Top) or "add-on boards" in the Raspberry Pi ecosystem. Raspberry Pi Shields or HATs can include the following:
Expanded Connections: They are used to increase the limited number of GPIO (General Purpose Input/Output) pins of the Raspberry Pi or provide input/output connections for specific purposes.
Components: Sensors, motor drivers, displays, relays, and other electronic components can be found in Shields or HATs to enhance the capabilities of the Raspberry Pi.
Interfaces: Interface modules (e.g., Wi-Fi, Bluetooth) used to communicate with specific devices or systems can be integrated into the Raspberry Pi.
Customized Functions: Cards that perform customized functions for specific projects or applications can be developed. They can be used in projects such as weather stations or security cameras.
Raspberry Pi Shields or HATs help users expand, customize, and develop more complex applications for their projects. These types of boards enable the Raspberry Pi community to unleash their creativity and take their projects to the next level.
