Arduino Nano Sensor Shield Nano I/O Expansion Board Prototype Shield

This Nano Multi-Function expansion board is designed especially for Nano and solves the problem of wiring confusion when a variety of sensors are connected. Nano Breakout Board Lead out all digital IO ports and analog IO ports, each one with standard positive and negative power interfaces. Arduino Nano Sheild Lead out the I2C interface of the mainboard for a convenient connection. Arduino Nano Prototype Board is Increasing the DC power supply interface. Nano USB interface supply current is actually only 50MA, to bring high-current devices, such as the steering, is obviously insufficient. So the DC power connector provides an external power supply to ensure the stability of equipment operation.
