Arduino Nano IO Expansion Shield – Sensor & Servo Breakout Board

Instantly upgrade your Arduino Nano projects!

The Arduino Nano IO Expansion Shield breaks out all digital and analog pins into standard 3-pin headers (Signal, VCC, GND), allowing you to effortlessly connect servos, sensors, relays, and modules without breadboard mess or loose wiring.

Key Features:

• Standard 3-Pin Headers (SVG Layout): Every GPIO pin is grouped into Signal, VCC, and GND for direct plug-and-play connection of servo motors and sensor modules.

• External Power Jack: Equipped with an onboard DC jack (5.5 x 2.1 mm) for an external power supply. Essential for projects running multiple servos or power-hungry components without overloading the microcontroller's USB port.

• Expanded I2C & UART Interfaces: Dedicated pin headers for I2C (SDA/SCL) and serial communication (UART) ensure quick integration with LCD displays and wireless modules.

• Onboard Reset Button & Power LED: Easy access to the reset function and status indication, even when fully wired.

• Simple Installation: Simply press your Arduino Nano V3.0 into the female header sockets and start building right away.

Why Choose This Expansion Board?

This board overcomes the biggest limitation of compact microcontrollers: the lack of central power and ground points. It transforms a compact Nano into a structured prototyping platform, making it ideal for robotics, automation, and multi-sensor systems.

Technical Specifications:

• Compatibility: Arduino Nano V3.0 (and 100% compatible variants)

• Pin Headers: 14 Digital I/O (including PWM), 8 Analog Inputs

• Input Voltage: External DC jack (6V – 12V DC) or USB-powered

• Extra Interfaces: Dedicated I2C, UART, and Servo power rails

• Dimensions: approx. 57 x 53 mm

Note: Supplied without the Arduino Nano board.
