The Keyestudio Nano IO Shield (KS0250) is a compact terminal adapter expansion board designed specifically for the Arduino Nano, breaking out all Nano pins into clearly labeled, easy-to-use screw terminals, servo-style 3-pin connectors, and pin headers. No more wrestling with jumper wires on a crowded breadboard, simply plug your Arduino Nano into the shield and connect sensors, modules, servos, and peripherals directly via secure, stable connections.
Key Features:
- Full Arduino Nano pin breakout — every digital and analog pin accessible
- Servo-style 3-pin connectors — direct servo and sensor module connection
- Screw terminal connections — secure, stable wiring without loose jumpers
- Clearly labeled digital and analog interfaces — reduces wiring errors
- UART, SPI, I2C support — full communication interface accessibility
- External power input — powers servos, relays, and high-current modules independently
- Compact FR4 PCB — professional quality, robotics-friendly form factor
- SMD components — clean, professional board design
- Direct Arduino Nano plug-in — no soldering required for shield connection
- 5V DC operation — compatible with all standard Arduino Nano variants
