Arduino Nano V3.0 Prototype Shield Expansion Board

ARDUINO NANO V3.0 PROTOTYPE SHIELD is an input/output expansion board specially engineered for the compact Arduino Nano V3.0 microcontroller. It features female header sockets to snugly seat an Arduino Nano and breaks out every digital and analog pin into standardized 3-pin (Signal, VCC, GND) servo-style headers, alongside an external DC power barrel jack and dedicated I2C communication terminals for clean, solderless prototyping.

Key Features:

• Tailored Nano Socket: Dual female header rows perfectly matched to the pinout and spacing of Arduino Nano 3.0 / 2.x boards.
• 3-Pin Sensor Breakouts: All 14 digital and 8 analog I/O pins broken out into convenient 3-pin G-V-S headers for direct sensor and servo attachment.
• External DC Power Jack: Onboard 2.1mm DC barrel connector and screw terminals to deliver high current directly to servos and power-hungry modules.
• Dedicated I2C Port: Onboard 4-pin interface providing direct VCC, GND, SDA (A4), and SCL (A5) connections for I2C displays and sensors.
• Reset Switch: Integrated hardware reset button providing easy reboot access while the Nano is seated.
• Compact Footprint: Minimal footprint ideal for mounting inside enclosures, robotic chassis, and compact embedded setups.
