This NANO / UNO Multi-Purpose IO Expansion Shield designed explicitly to facilitate an easy connection between Arduino Nano and many other devices. This sensor shield provides an easy connection with Arduino Nano direct. In case if your seal the Pin of board also, it is Compatible with Arduino Duemilanove 2009 and UNO R1.
This shield features 8 analog pins, 13 digital I/O pins, and Aref with 3 pin connectors (GND, Vcc, and Signal). Each functional module consists of a buckled port with an independent I2C port with 4pins (SDA, SCL, GND, and Vcc) and UART (Rx, Tx, Vcc, and GND). It also comes with an onboard reset button and a female jack provided for the external power supply. These make the connections easier, secure, and more professional looking.
Using this expansion board, we can easily solve wiring confusing problem, while connecting the NANO with a variety of sensor, as you develop works of the weapon. You can use this expansion board, by just combining Arduino and sensors module using special cables. This is because concrete circuit details achieve by the corresponding sensors module. So you only need to consider that how to read data coming from the sensor by the program in Arduino. This NANO / UNO Multi-Purpose IO Expansion Shield is the perfect choice for Arduino beginners. As you do not have a headache for the cumbersome and complex circuit connection.
