Arduino Multifunctional Expansion Board Shield | Multi-Function Shield for Arduino Uno

Arduino Multifunctional Expansion Board Shield

Get more out of your Arduino Uno with the Multifunctional Expansion Shield — a versatile add-on board that packs a wide range of components and breakout interfaces onto a single plug-in shield. Whether you're learning Arduino or building a rapid prototype, this board gives you everything you need in one place.

Key Features

• 4-Digit 7-Segment Display — for showing numbers, counters, timers, and sensor values
• 4x Push Buttons — for user input and interactive control
• 10x LEDs — for visual indicators, bar graphs, and status displays
• Buzzer — for audio alerts, tones, and alarms
• Potentiometer — analog input for variable control (brightness, speed, etc.)
• IR Receiver — for remote control input via infrared signals
• DS18B20 Temperature Sensor socket — for onboard temperature sensing
• Servo motor connector — dedicated 3-pin header for servo control
• Sensor expansion headers — breakout pins for connecting external sensors and modules
• Plug-in shield design — fits directly onto Arduino Uno / Mega headers
• Arduino IDE compatible — works with standard libraries
