Features : 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. This expansion shield provides: *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 *I2C expansion Pin *AREF output *3.3V output Package Included: 5 * Nano I / O Expansion Sensor Shield

5 I2C expansion Pin. 1 Servo power input. 6 PWM Pin. 8 analog Pin with power output and GND. 14 I/O Pin (servo type with GND, power and signal).
