Arduino Nano R3 - clone

The Arduino Nano is a small, complete, breadboard-friendly sign based on the ATmega328. This board uses the same chip as the UNO, but comes in a different package. This board has no DC power jack, and is controlled with a Mini-USB cable.

Properties



 

Microcontroller	ATmega328P
Operating Voltage	5V
Input Voltage (recommended)	7-12V
Input Voltage (limits)	6-20V
Digital I / O Pins	14 (of which 6 may give PWM output)
Analog Input Pins	8
DC Current per I / O Pin	40 mA
DC Current for 3.3V Pin	50 mA
Flash Memory	32 KB (ATmega328) 0.5 KB is used by the bootloader
SRAM	2 KB (ATmega328P)
EEPROM	1 KB (ATmega328P)
Clock Speed	16 MHz

It concerns the 3rd revision (newest) with the following adjustments:

• Stronger RESET circuit.
• Added SDA and SCL pins at the AREF pin and 2 new pins at the RESET pin, namely the IOREF pin, allowing shields to adjust to the voltage from the board. In the future, shields are compatible with both the 5v and 3.3v versions. The 2nd pin is not connected and is reserved for future updates.

This arduino is a clone, which means that this sign was not built in the original factory. The only difference between original and clones is that these Arduinos are cheaper. All components and circuits are otherwise identical.
