Nano I / O Expansion sensor Shield For Arduino

Nano I / O Expansion sensor Shield For ArduinoDESCRIPTION The Arduino I O Expansion Shield provides an easy way to connect sensors, servos and RS485 device to Arduino board. It expands Arduinos Digital I O and Analog Input Pins with Power and GND. It also provides separate PWM Pins which are compatible with standard servo connector. Another unique feature is that the I O shield has a build in RS485 converter which allows Arduino communicating with RS485 devices. The communication socket provides

23 general purpose I/O lines

We've updated the Simple board to create the LilyPad USB by replacing the classic ATMega328 with the new ATMega32U4

The pins have

small current at the base side is used to control large current at the emitter and collector side

you can also retrieve the image of a fingerprint and even pull raw images from the optical sensor
