The Arduino Nano is small complete and breadboard friendly

It has more or less the same functionality of the Arduino Duemilanove but

in a different package. It lacks only a DC power jack, and works with a USB type-C cable.

Specs

Microcontroller : ATmega328

Architecture : AVR

Operating Voltage : 5V

Flash Memory : 32KB of which 2KB used by bootloader

SRAM : 2KB

Clock Speed : 16MHz

Analog IN Pins : 8

EEPROM : 1KB

DC Current per I/O Pins : 20mA (I/O Pins)

Input Voltage : 5-12V

Digital I/O Pins : 22 (6 of which are PWM)

PWM Output : 6

Every single Arduino Nano gets tested with the blink script before there dispatched

so when it turns up and you plug it in, it will have the flashing LED.

This Arduino Nano is only returnable if the pin headers have not been soldered in.

So please test before fitting the pin headers please.
