Expansion Board Nano ATmega328 IO Wireless
This shield is specifically designed to enhance the functionality of the Arduino Nano, making it easier to connect external sensors, actuators, and modules. It provides clearly labeled and organized 3-way headers (Signal, Voltage, Ground), ideal for RC servo and sensor connections. The shield also features separate 4-way headers for UART and I2C communication, ensuring ease of integration with other devices.
Every IO pin is expanded to include power and ground, reducing wiring complexity. The shield supports external powering through a standard 2.1mm DC barrel jack with reverse polarity protection and smoothing capacitors. Additionally, it includes an independent 3.3V voltage regulator capable of supplying up to 500mA — far more than the Arduino Nano's native 3.3V output (50mA max).
Designed in a traditional shield form factor, it also includes side pads for compatibility with Arduino UNO headers. Clear pin labeling ensures intuitive setup for beginners and experts alike.
