Arduino and Microcontroller Supplies: Boards, Sensors, Modules, Kits and Raspberry Pi Accessories
Arduino and other microcontroller platforms let students, makers, engineers and teachers build electronic projects, from blinking LEDs to robots, weather stations and home automation. This category covers boards and shields, sensor modules, power, relay and motor modules, component kits, Raspberry Pi accessories, displays and wireless modules.
Boards and shields
Arduino Uno is the classic beginner board, while Nano is compact for small projects and Mega offers more pins for complex builds. ESP32 and ESP8266 boards add Wi-Fi and Bluetooth for IoT projects. Shields stack on top of boards to add functions such as motor control and displays.
Sensor modules
Sensors measure temperature, humidity, distance, light, motion, gas, sound and more. Check the operating voltage and interface (analogue, digital, I2C, SPI).
Power, relay and motor modules
Power modules supply stable voltage, relay modules switch higher-power devices such as lamps and pumps, and motor modules drive DC motors, servos and stepper motors. Use proper isolation when switching mains voltage, and only if you have the knowledge to do so safely.
Displays and wireless modules
LCD, OLED and LED display modules show information, while transmitters and receivers add radio communication.
Component kits
Starter kits include a board, sensors, components, wires and tutorials, making them the easiest way to begin. They are popular in schools and coding clubs.
Raspberry Pi accessories
Cases, power supplies, cooling fans, cameras, displays and HATs extend Raspberry Pi single-board computers.
Compatibility
- 3.3 V and 5 V logic: some modules need level shifters.
- Libraries: check that libraries are available for your board.
- Pin requirements: ensure your board has enough pins.
Practical tips
Start with a kit and tutorials. Use a breadboard for prototyping. Read datasheets for each module.
Arduino projects teach electronics and programming in a hands-on way that builds practical skills.
