difference-between-Arduino-UNO-and-Arduino-nano Arduino Nano Communication The main differences between these two are listed in the following table. The programming of UNO can be done with a USB cable whereas Nano uses the mini USB cable. So Uno boards use more space on the system. Because Arduino Uno size is double to nano board. The main difference between these two is the size. The Arduino Nano board is similar to an Arduino UNO board including similar microcontroller like Atmega328p. IIC (A4, A5): These pins are used for supporting TWI communication.ĪREF: This pin is used to give reference voltage to the input voltage Difference between Arduino UNO and Arduino Nano
Serial Pins (Tx, Rx): These pins are used to transmit & receive TTL serial data. I/O Pins (Digital Pins from D0 – D13): These pins are used as an i/p otherwise o/p pins. RST Pin( Reset): This pin is used to reset the microcontrollerĪnalog Pins (A0-A7): These pins are used to calculate the analog voltage of the board within the range of 0V to 5V
And other development boards are AVR Development Board, PIC Development Board, Raspberry Pi, Intel Edison, MSP430 Launchpad, and ESP32 board.
Other Arduino boards mainly include Arduino Mega, Arduino Pro Mini, Arduino UNO, Arduino YUN, Arduino Lilypad, Arduino Leonardo, and Arduino Due. It is a small size board and also flexible with a wide variety of applications. This microcontroller is also used in Arduino UNO. It can be built with a microcontroller like Atmega328. anything besides an upload of new code), it will intercept the first few bytes of data sent to the board after a connection is opened.Arduino Nano is one type of microcontroller board, and it is designed by. While it is programmed to ignore malformed data (i.e. For the following half-second or so, the bootloader is running on the Nano.
When the Nano is connected to a computer running Mac OS X or Linux, it resets each time a connection is made to it from software (via USB).
When this line is asserted (taken low), the reset line drops long enough to reset the chip. One of the hardware flow control lines (DTR) of the FT232RL is connected to the reset line of the ATmega328 via a 100 nanofarad capacitor. Rather than requiring a physical press of the reset button before an upload, the Arduino Nano is designed in a way that allows it to be reset by software running on a connected computer. The Arduino software includes a Wire library to simplify use of the I2C bus.
The ATmega328 also support I2C and SPI communication. A SoftwareSerial library allows for serial communication on any of the Nano's digital pins. The RX and TX LEDs on the board will flash when data is being transmitted via the FTDI chip and USB connection to the computer (but not for serial communication on pins 0 and 1). The Arduino software includes a serial monitor which allows simple textual data to be sent to and from the Arduino board.
An FTDI FT232RL on the board channels this serial communication over USB and the FTDI drivers (included with the Arduino software) provide a virtual com port to software on the computer. The ATmega328 provide UART TTL (5V) serial communication, which is available on digital pins 0 (RX) and 1 (TX). The Arduino Nano has a number of facilities for communicating with a computer, another Arduino, or other microcontrollers. Flash memory: 32 KB, of which 0.5 KB is used by bootloader.Digital I/O pins: 14 (6 optional PWM outputs).Microcontroller: Microchip ATmega328P.
