ARDUINO Nano 3.0 Development Board
Build faster prototypes with the ARDUINO Nano 3.0 board featuring an ATmega328 microcontroller, 16MHz clock, and compact 43x33mm dimensions.
The ARDUINO Nano 3.0 is an intelligent development board designed for building faster prototypes within the smallest dimensions. As the oldest member of the Nano family, it provides ample interfaces for your breadboard-friendly applications.
At the heart of the board is an ATmega328 microcontroller clocked at a frequency of 16MHz, offering functionalities comparable to the Arduino Duemilanove. It features a high-performance, low-power 8-bit processor capable of achieving up to 16 MIPS. The board is equipped with 20 digital input/output pins, 8 analogue pins, and a convenient Mini-B USB connection for programming and power.
Memory and Interfaces
- 32kB Flash memory (2kB used by the bootloader)
- 2kB internal SRAM and 1kB EEPROM
- 32 x 8 general purpose working registers
- Real time counter with separate oscillator
- Six PWM channels, programmable serial USART, and SPI serial interface
Power and Environment
The board supports a 7-15V unregulated external power supply (pin 30) or a 5V regulated external power supply (pin 27). It operates within conservative thermal limits of -40°C to 85°C, making it suitable for demanding environments.
Please note: From January 2018, the Arduino Nano ships with an upgraded bootloader. Arduino AVR Core 1.16.21 or later is required. Measuring just 43 mm x 33 mm x 15 mm and weighing only 50 grams, this compact board is perfect for space-constrained projects.
