The Nano 328P Expansion Adapter Breakout Board IO Shield acts as a breakout board for the Arduino Nano microcontroller. There are several different options for power input and the footprint of this expansion adapter breakout board. Separate pinout includes 7.2 to 9V and GND pins for easy connection to servos.

In addition, Separate pinout includes 7.2 to 9V and GND pins for easy connection to sensors and Bluetooth devices.

The Nano 328P breakout boar unit comes fully assembled. Arduino Nano IO Expansion Shield is specifically designed to facilitate an easy connection between  Arduino Nano and many other devices. In essence, it expands the Arduino 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. The board offers: 14 I/O Pin (servo type with GND, power, and signal). 8 analog Pin with power output and GND. 6 PWM Pin. 1 Servo power input. 5 I2C expansion Pin. 1 AREF output. 1 3.3V output. Specifications: Input Voltage(V) : 3.3 ~ 5 No. of Analog Pins : 8 No. of PWM Pin : 6 Length (mm) : 58 Width (mm) : 54 Height (mm) : 12 Weight (gm) : 15 Package Includes : 1 x Nano 328P Expansion Adapter Breakout Board IO Shield
