įor a quick reference, coloured version of the Arduino Uno R3 schematic is given below:

The Complete archive of the EAGLE schematic diagram and board layout is provided on the Arduino website. Pin mapping from AVR pins to Arduino headers) and other hardware details of the board. A 16 MHz crystal is installed on the board.Īrduino Uno dimensions measure 68.6 mm X 53.4 mm.įollowing figure shows the Arduino Uno R3 pinout (i.e. It also has 6 PWM outputs multiplexed on to the digital IO pins. It has 14 digital IO pins (PORTD – 8pins, PORTC – 6 pins, PORTB – 5pins), 6 Analogue input pins, which can be sampled using on-chip ADC. This MCU has 32KB of flash, 2KB of SRAM and 1 KB of EEPROM. This blog post collects all the trivial information necessary for you to get started with Arduino Uno.Īrduino Uno is based on ATmega328P Atmel AVR family microcontroller (MCU). This is an Integrated Development Environment which offers compilation-to-download functionality with a rich set of library functions.Ī fancy name for a – simplified C language based programming platform with a rich set of libraries for accessing microcontroller features and third party hardware chips!īecause of simplicity, Arduino platform quickly became famous. It has a 32 bit ARM Cortex M3 processor with 512KB of flash, 100KB of SRAM, Ethernet, CAN, USB minihost, highspeed SD/SDIO/MMC, USART, SPI, TWI, ADC, DAC, timers, temperature sensor and touch peripherals. This board is designed around the SAM3X8E Smart ARM (SAM) microcontroller. It is an 8 bit microcontroller with 256KB of flash, 8KB of SRAM, 4KB of EEPROM, timers, ADC, DAC, I2C, SPI, UART, and touch peripherals. This board is designed around the ATmega2560 AVR microcontroller. It is an 8 bit microcontroller with 32KB of flash, 2KB of SRAM, 1KB of EEPROM, timers, ADC, I2C, SPI, and UART peripherals.

This board is designed around the ATmega328 AVR microcontroller. Examples of some of the most popular Arduino Hardware boards are – Arduino Uno It comprises of Hardware boards and Software tools. Arduino is an Open Source embedded development platform which is easy-to-use.
