WYPH Nano I/O Expansion Sensor Shield Module for Arduino UNO R3 Nano V3.0 / Nano Pro Compatible UNO R1 Duemilanove 2009 (Expansion Board 3pcs)

Feature:
This breakout board is much better than using a breadboard - because all of the pins are available in "triplets" with the Gnd and VCC, making it convenient to connect sensors and outputs with DuPont wires or server cables (watch the polarity and pinouts).
When you put an Arduino Nano in the black socket and this board allows you to easily connect to the various I/O pins and power. It has a 2.1mm x 5.5mm socket to apply power (just like an Arduino Uno) and a 3.3v regulator to suppliment the 5v regulator on the Nano. The unpopulated pads along the outer edge are the correct spacing for 0.1 inch female headers and will allow you to use any Arduino UNO compatible shield with a Nano.TLDR, it makes prototyping with an Arduino Nano easier.

Specifications:
- 14 I/O Pin (servo type with GND, power and signal)
- 3.3V output
- 8 analog Pin with power output and GND
- 6 PWM Pin
- 1 Servo power input
- I2C expansion Pin
- AREF output
