The 14 digital input/output pins can be used as input or output pins by using pinMode(), digitalRead() and digitalWrite() functions in arduino programming. Has 14 digital input/output pins (out of which 6 only can be used as PWM output's), 6 analog input pins, a USB connection, A Power barrel jack, an ICSP header and a reset button. Along with ATmega328P, it consists other components such as crystal oscillator, serial communication, voltage regulator, etc. Other Development BoardsĪrduino Uno is a microcontroller board based on 8-bit ATmega328P microcontroller. Note: More technical information can be found in the Arduino Uno Datasheet linked at the bottom of this page. To provide reference voltage for input voltage.Īrduino Uno Board Internal Specifications Microcontroller
Used to receive and transmit TTL serial data. Used to provide analog input in the range of 0-5V Vin: Input voltage to Arduino when using an external power source.ĥV: Regulated power supply used to power microcontroller and other components on the board.ģ.3V: 3.3V supply generated by on-board voltage regulator.
