This is a non-exhaustive list of Arduino boards and compatible systems. It lists boards in these categories: Released under the official Arduino name; Arduino "shield" compatible; Development-environment compatible; Based on non-Atmel processors; Where different from the Arduino base feature set, compatibility, features, and licensing details ...
The AVR Dragon provides in-system serial programming, high-voltage serial programming and parallel programming, as well as JTAG or debugWIRE emulation for parts with 32 KB of program memory or less. ATMEL changed the debugging feature of AVR Dragon with the latest firmware of AVR Studio 4 - AVR Studio 5 and now it supports devices over 32 KB of ...
This was an early example of a medium-scale integrated circuit. Another popular chip was the SCN2651 from the Signetics 2650 family. An example of an early 1980s UART was the National Semiconductor 8250 used in the original IBM PC's Asynchronous Communications Adapter card. [5] In the 1990s, newer UARTs were developed with on-chip buffers.
This uses the same ATmega328 as late-model Duemilanove, but whereas the Duemilanove used an FTDI chip for USB, the Uno uses an ATmega16U2 (ATmega8U2 before rev3) programmed as a serial converter.

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.
It is sometimes called a four-wire serial bus to contrast with three-wire variants which are half duplex, and with the two-wire I²C and 1-Wire serial buses. Typical applications include interfacing microcontrollers with peripheral chips for Secure Digital cards, liquid crystal displays , analog-to-digital and digital-to-analog converters ...
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]
For example, the program counter is not directly writeable in many microcontroller architectures. Instead, the programmer uses instructions such as return from subroutine, jump, or branch to modify the program counter. For another example, the condition code register might not be directly writable, instead being updated only by compare ...
