Arduino Nano Sensor Shield I/O Expansion Board

Expand Your Arduino Nano with Easy Sensor Connections

The Arduino Nano Sensor Shield (Nano I/O Expansion Board) is a plug-and-play breakout board designed specifically for the Arduino Nano. It breaks out all Nano pins into convenient 3-pin sensor headers (VCC, GND, Signal), allowing you to connect sensors, servos, and modules directly — no breadboard or messy wiring required.

Key Features

• Direct plug-in socket for Arduino Nano (fits all Nano variants)
• All digital and analog pins broken out as 3-pin headers (VCC, GND, SIG)
• Dedicated power rails: 5V and 3.3V available on headers
• Onboard IIC / I2C interface (SDA, SCL) for connecting OLED, RTC, etc.
• Onboard UART header (TX, RX) for serial communication
• Servo-compatible headers on PWM pins
• LED power indicator
• Compact design — minimal footprint increase over Nano itself

Common Applications

• Rapid prototyping with Arduino Nano
• Multi-sensor projects (DHT11, ultrasonic, PIR, soil moisture, etc.)
• Servo motor control
• OLED and LCD display connections via I2C
• Robotics and automation projects

Package Includes

• 1 × Arduino Nano I/O Sensor Shield Expansion Board

Note: Arduino Nano board is not included. Compatible with Arduino Nano V3.0, Nano Every, and most Nano-footprint clones.
