The word "uno" means "one" in Italian and was chosen to mark a major redesign of the Arduino hardware and software. [7] The Uno board was the successor of the Duemilanove release and was the 9th version in a series of USB-based Arduino boards. [8] Version 1.0 of the Arduino IDE for the Arduino Uno board has now evolved to newer releases. [4]
Arduino Uno compatible, D13 pin isolated with a MOSFET of which can also be used as an input. KitTen [126] ATmega328P Freetronics Includes both 3.3 V and 5 V regulators for shields, D13 pin isolated with a MOSFET of which can also be used as an input. Can be connect to Arduino using CAT5 cable. [127] EtherDue [128] ATSAM3X8E [16] Freetronics
Arduino (/ ɑː r ˈ d w iː n oʊ /) is an Italian open-source hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices.
Arduino Mega compatible board with 16 extra I/O pins and the same a board size as the Arduino Uno. As with the Arduino Mega, most shields that were designed for the Duemilanove, Diecimila, or Uno will fit, but a few shields will not fit because of interference with the extra pins.

ATtiny (also known as TinyAVR) is a subfamily of the popular 8-bit AVR microcontrollers, which typically has fewer features, fewer I/O pins, and less memory than other AVR series chips. The first members of this family were released in 1999 by Atmel (later acquired by Microchip Technology in 2016).
ATmega328 is commonly used in many projects and autonomous systems where a simple, low-powered, low-cost micro-controller is needed. Perhaps the most common implementation of this chip is on the popular Arduino development platform, namely the Arduino Uno, Arduino Pro Mini [4] and Arduino Nano models.
6- and 10-pin ISP header diagrams The in-system programming (ISP) programming method is functionally performed through SPI , plus some twiddling of the Reset line. As long as the SPI pins of the AVR are not connected to anything disruptive, the AVR chip can stay soldered on a PCB while reprogramming.
A GPIO pin's state may be exposed to the software developer through one of a number of different interfaces, such as a memory-mapped I/O peripheral, or through dedicated IO port instructions. Some GPIOs have 5 V tolerant inputs: even when the device has a low supply voltage (such as 2 V), the device can accept 5 V without damage.
