ARDUINO NANO

RAW	For supplying a raw (regulated) voltage to the board
VCC	The regulated 3.3 or 5 volt supply
GND	Ground pins
RX	Used to receive TTL serial data
TX	Used to transmit TTL serial data
2 and 3	Digital I/O pins. These pins can also be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value
3, 5, 6, 9, 10, and 11	Digital I/O pins. They can also be configured to provide 8-bit PWM output
10, 11, 12 and 13	Digital I/O pins. They can also be configured as SPI pins; 10 – (SS), 11 – (MOSI), 12 – (MISO) and 13 – (SCK)
A0 to A3	Analog input pins
A4 and A5.	Analog input pins. They can also be used as IIC pins; A4 – (SDA) and A5 – (SCL).
A6 and A7	Analog input pins
Reset	The microcontroller can be reset by bringing this pin low
