Arduino Nano V3.3

Description

Arduino Nano is the breadboard version with an integrated USB port. It has more or less the same features as the Arduino Duemilanove, but in a different package. It automatically selects the power source. It uses an ATMEGA328 processor with 32 kB of memory for the program. It has 14 digital input/output pins (6 of which can be used as PWM outputs), 8 analog inputs, and a 16 MHz oscillator. It lacks a power jack and is programmed via a mini USB cable.

FAQ

• The newly purchased board cannot be programmed via USB
  This is due to a bootloader update. Since a major bootloader update was made, the IDE cannot program the board, so you need to update the “Arduino AVR Boards” from your board manager to the latest version. After the update, select “ATmega328P” as the processor type, not “ATmega328P (Old Bootloader)”.
