The version 1.0 of Arduino Software (IDE) and Uno board both are considered as the reference versions of Arduino, which evolved with time with new features.

Uno stands for one in Italian and this name was picked for the release of Arduino Software (IDE) 1.0. The new version includes four solder pads JP2 attached with the pins PB4 to PB7 of the USB ATmega. Know that Arduino UNO REV3 is an advanced version of Arduino UNO. The robust and clean design helps you shape your ideas into reality. Moreover, 6 analog input pins are available on the board and the clock frequency is 16MHz.Īrduino UNO is one of the most used boards from the Arduino family. It carries 14 digital I/O pins out of which 6 can be used as PWM outputs.

In this post, I’ll detail the Introduction to Arduino UNO REV3.Īrduino Uno REV 3 is an Arduino board based on the microcontroller ATmega328P.
