Development boards
A small board with a processor and pins on which you build your own electronic project — from a blinking LED to a smart home. Development boards are the foundation for programming, robotics and teaching electronics. They include the popular Arduino, the Raspberry Pi single-board computers, the energy-saving ESP32 chips with Wi-Fi and other microcontrollers. They differ in performance, the number of inputs and outputs, connectivity and the environment they're programmed in. You can choose based on the complexity of the project and on whether you're starting out or building something advanced.
Development boards
A single small board fitted with a processor, memory and a row of pins opens the way to devices built with your own hands. Development boards are used for programming, controlling motors and sensors, building robots and a smart home, and are a popular aid in teaching electronics. They're valued by beginners, hobbyists, students and experienced makers who want to get their own idea going.
The range covers several different types. Arduino is a microcontroller ideal for simple control of electronics and the first steps in programming. Raspberry Pi is a full single-board computer with an operating system that handles more demanding projects and connecting a display too. The ESP32 and ESP8266 chips have built-in Wi-Fi and Bluetooth, so they suit internet-connected projects. They're complemented by smaller microcontrollers for low-power circuits.
The inputs, outputs and the way you program are crucial. GPIO pins let you connect sensors, buttons, displays or relays, and the connectivity decides whether the board communicates over Wi-Fi, Bluetooth or only by cable. Arduino is programmed in the clear Arduino IDE environment, Raspberry Pi handles Python and common applications. Sensors, modules and connecting cables go well with the boards.
When choosing, start from the complexity of the project and your experience. For the first attempts and simple control a basic Arduino is enough, for internet projects reach for a board with Wi-Fi, for more compute-heavy tasks a Raspberry Pi. Consider how many pins and what connectivity you'll need and whether you'll add a starter kit with sensors. A well-chosen board makes the first steps and the realisation of an ambitious project easier.
