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 ]
A reference designator unambiguously identifies the location of a component within an electrical schematic or on a printed circuit board.The reference designator usually consists of one or two letters followed by a number, e.g. C3, D1, R4, U15.

A digital current loop uses the absence of current for high (space or break), and the presence of current in the loop for low (mark). [1] This is done to ensure that on normal conditions there is always current flowing and in the event of a line being cut the flow stops indefinitely, immediately raising the alarm of the event usually as the heavy noise of the teleprinter not being synchronized ...
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.
A compound DC motor connects the armature and fields windings in a shunt and a series combination to give it characteristics of both a shunt and a series DC motor. [5] This motor is used when both a high starting torque and good speed regulation is needed. The motor can be connected in two arrangements: cumulatively or differentially.
MCU I/O Voltage column - Microcontrollers on official Arduino boards are powered at a fixed voltage of either 3.3 or 5 volts, though some 3rd party boards have a voltage selection switch. The voltage rating of the microcontroller is stated inside parenthesis, though Arduino boards don't support this full range. MCU Clock column - MHz means 10 6 ...
A motor requiring a DC power supply for operation is termed a DC motor. DC motors are widely used in control applications like robotics, tape drives, machines and many more. Separately excited DC motors are suitable for control applications because of separate field and armature circuit. [1] Two ways to control DC separately excited motors are ...
