Description: 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 Size:6x5.3x1.3cm Package Included: 6x I/O Extension Board Expansion Module

OUTPUT --- 3.3V output,Size:6x5.3x1.5cm(2.36 x 2.08 x 0.59inch). 14 I / O Pin --- servo type with GND, power and signal,Lead I2C interface to main board, convenient and I2C device connection. 8-PIN ANALOG OUTPUT --- with output power and GND,1 Servo power input, the barrel connecter input voltage range is 6-12 volts producing a stabilized 5v at 1A. Increase the DC power interface - the power supply current of the USB interface on the board is actually only 50MA, which is not enough when a high-current device is needed. In this case, an external power supply is provided at the DC power interface to ensure the stable running of the device. for Nano I/O EXPANSION SENSOR --- Lead out all digital IO ports and analog IO ports, each IO port has a standard positive and negative power supply interface Lead out the I2C interface on the main board to facilitate the connection with the I2C device.
