Bring this line LOW to reset the microcontroller. There are a couple of other pins on the board: Support I 2C (TWI) communication using the Wire library (documentation on the Wiring website). Additionally, some pins have specialized functionality: By default they measure from ground to 5 volts, though is it possible to change the upper end of their range using the analogReference() function. The Nano has 8 analog inputs, each of which provide 10 bits of resolution (i.e. When the pin is HIGH value, the LED is on, when the pin is LOW, it's off. There is a built-in LED connected to digital pin 13. These pins support SPI communication, which, although provided by the underlying hardware, is not currently included in the arduino language. Provide 8-bit PWM output with the analogWrite() function. See the attachInterrupt() function for details. These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value. These pins are connected to the corresponding pins of the FTDI USB-to-TTL Serial chip. Used to receive (RX) and transmit (TX) TTL serial data. In addition, some pins have specialized functions: Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms. Input and OutputĮach of the 14 digital pins on the Nano can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. As a result, when running on external (non-USB) power, the 3.3V output (which is supplied by the FTDI chip) is not available and the RX and TX LEDs will flicker if digital pins 0 or 1 are high. The FTDI FT232RL chip on the Nano is only powered if the board is being powered over USB. The power source is automatically selected to the highest voltage source. The arduino Nano can be powered via the Mini-B USB connection, 6-7V unregulated external power supply (pin 30), or 5V regulated external power supply (pin 27). Specifications:ģ2 KB ( ATmega328) of which 2 KB used by bootloader It lacks only a DC power jack, and works with a Mini-B USB cable instead of a standard one. It has more or less the same functionality of the arduino Duemilanove, but in a different package. Arduino Nano 3.0 is now shipping with ATMEGA328.The arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (arduino Nano 3.0). The power source is automatically selected to the highest voltage source.Īrduino Nano 3.0 Schematic Arduino Nano 3.0 User Manual (pinout and dimensions) Eagle design files ATmega328 datasheetĪrduino Nano 3.0 Assembly from Gravitech on Vimeo. The Arduino Nano can be powered via the mini-B USB connection, 6-20V unregulated external power supply (pin 30), or 5V regulated external power supply (pin 27). Standard 0.1” spacing DIP (breadboard friendly).ICSP header for direct program download.Small mini-B USB for programming and serial monitor. Green (TX), red (RX) and orange (L) LED.Automatic reset during program download.You end up paying less with Nano than Mini and USB combined! That make it easier to hack and more affordable. This new version 3.0 comes with ATMEGA328 which offer more programming and data memory space. It’s got a pin layout that works well with the Mini or the Basic Stamp (TX, RX, ATN, GND on one top, power and ground on the other). Nano’s got the breadboard-ability of the Boarduino and the Mini+USB with smaller footprint than either, so users have more breadboard space. The Nano is automatically sense and switch to the higher potential source of power, there is no need for the power select jumper. It has everything that Diecimila/Duemilanove has (electrically) with more analog input pins and onboard +5V AREF jumper. It is a smallest, complete, and breadboard friendly. CreditsĪrduino Nano is a surface mount breadboard embedded version with integrated USB. Flash, Processing, MaxMSP).Īrduino received an Honory Mention in the Digital Communities section of the 2006 Ars Electronica Prix. Arduino projects can be stand-alone or they can communicate with software on running on a computer (e.g. The microcontroller on the board is programmed using the Arduino programming language (based on Wiring) and the Arduino development environment (based on Processing). It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments.Īrduino can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators. A0-A7 pins compatible with Arduino Stamp and Pro MiniĪrduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software.The new version of Arduino Nano 3.0 is here!
