NANO Shield Expansion Board for ARDUINO NANO

grabcad

The Nano Multi-Function expansion board is specifically designed for Arduino Nano, simplifying the complex wiring when multiple sensors are connected. It exposes all digital and analog IO ports with standard positive and negative power interfaces. The I2C interface of the mainboard is also exposed for easy connection. Additionally, an external DC power supply interface is included to ensure stable operation of high-current devices like motors, as the Nano USB interface can only provide 50mA of current, which is insufficient for such devices.
