39+ Arduino Uno R3 Microcontroller Board Pics. Arduino uno is a microcontroller board based on the atmega328p ( datasheet ). The board is equipped with sets of digital and analog input/output (i/o) pins that may be interfaced to various expansion boards (shields) and other circuits.
In rare cases even if you mess up with the board you can just change the atmega 328p microcontroller for few bucks ( around 6$/200 inr) as uno is a surface mount version with dip package.
The arduino uno is a microcontroller board based on the atmega328 microchip. Arduino uno is a microcontroller board based on the atmega328p ( datasheet ). Great for learning the basics of how sensors and actuators work, and an essential arduino uno is the most used and documented board in the world. Uno means one in italian and was chosen to mark the release of arduino software (ide) 1.0.
