The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller (MCU) and developed by Arduino.cc and initially released in 2010. [2] [3] The microcontroller 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. [1]
The first Arduino board based on an ARM processor. Features 2 channel 12-bit DAC, 84 MHz clock frequency, 32-bit architecture, 512 KB flash and 96 KB SRAM. Unlike most Arduino boards, it operates on 3.3 V and is not 5 V tolerant. Arduino Yún [21] ATmega32U4, [22] Atheros AR9331 16 MHz, 400 MHz Arduino 68.6 mm × 53.3 mm [ 2.7 in × 2.1 in ]
Japanese Arduino compatible kit using Uno board setting. Includes two mini-B USB sockets, 1602 LCD socket, 5 V or 3.3 V power selection, breadboard area. Cosmo Black Star [75] JT5 [76] ATmega328 16 MHz Arduino layout-compatible board. Based on the Arduino Duemilanove. CraftDuino [77] Manufactured and sold by RoboCraft Team. 16 MHz CT UNO
The default bootloader of the Arduino Uno is the Optiboot bootloader. [33] Boards are loaded with program code via a serial connection to another computer. Some serial Arduino boards contain a level shifter circuit to convert between RS-232 logic levels and transistor–transistor logic level signals.
The Make Controller Kit with an Atmel AT91SAM7X256 microcontroller.. A single-board microcontroller is a microcontroller built onto a single printed circuit board.This board provides all of the circuitry necessary for a useful control task: a microprocessor, I/O circuits, a clock generator, RAM, stored program memory and any necessary support ICs.
serial input/output such as serial ports ; other serial communications interfaces like I²C, Serial Peripheral Interface and Controller Area Network for system interconnect; peripherals such as timers, event counters, PWM generators, and watchdog; clock generator – often an oscillator for a quartz timing crystal, resonator or RC circuit

The final layout of early ICs and PCBs was stored as a tape-out of Rubylith on transparent film. Gradually, electronic design automation automated more and more of the place-and-route work. At first, it merely sped up the process of making many small edits without spending a lot of time peeling up and sticking down the tape.
