Nano IO Expansion Shield is specifically designed to facilitate an easy connection between Nano and many other devices. In essence, it expands the Nano controller to link those devices in a simple and trouble free manner. It is a perfect companion of Nano breadboard and compatible with both Arduino Nano v2.x and v3.x.
Make sure this fits by entering your model number.
★14 I/O Pin (servo type with GND, power and signal).
★8 pin analog with output power and GND.
★Output all digital IO ports and analog IO ports, each IO port has a standard positive and negative power interface.
★Output the I2C interface on the motherboard to facilitate the connection with I2C devices. the I2C interface on the motherboard to facilitate the connection with I2C devices.
★Increase the DC power supply interface. The USB interface power supply current on the NANO board is actually only 50MA. It is obviously insufficient when devices with large currents such as steering gears are required. At this time, an external power supply is provided at the DC power supply interface.
