    keyestudio Uno R3 is a microcontroller board based on the ATmega328 fully compatible with ARDUINO UNO REV3. 
    It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, 2 ICSP headers and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. 
    Note that the two ICSP headers are separately used to program the firmware to ATMEGA16U2-MU and ATMEGA328P-PU, but generally the two chips have been programmed well.
    The Uno R3 differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega16U2 programmed as a USB-to-serial converter.
    The UNO is the best board to get started with electronics and coding. If this is your first experience tinkering with the platform, the UNO is the most robust board you can start playing with.

    Element and Pin Interfaces

    Here is an explanation chart of what every element and interface of the board does: 
    Ks0001-pinout.png

    KS0001 5-1.pngICSP (In-Circuit Serial Programming) Header

    In most case, ICSP is the AVR,an Arduino micro-program header consisting of MOSI, MISO, SCK, RESET, VCC, and GND. It is often called the SPI (serial peripheral interface) and can be considered an "extension" of the output. In fact, slave the output devices under the SPI bus host.
    When connecting to PC, program the firmware to ATMEGA328P-PU.

    KS0001 5-2.pngPower LED Indicator

    Powering the Arduino, LED on means that your circuit board is correctly powered on. If LED is off, connection is wrong.

    KS0001 5-3.pngDigital I/O

    Arduino UNO has 14 digital input/output pins (of which 6 can be used as PWM outputs). These pins can be configured as digital input pin to read the logic value (0 or 1). Or used as digital output pin to drive different modules like LED, relay, etc. The pin labeled “〜” can be used to generate PWM.

    KS0001 5-4.pngGND ( Ground pin headers)

    Used for circuit ground

    KS0001 5-5.pngAREF

    Reference voltage (0-5V) for analog inputs.

    KS0001 5-6.pngSDA

    IIC communication pin

    KS0001 5-7.pngSCL

    IIC communication pin

    KS0001 5-8.pngICSP (In-Circuit Serial Programming) Header

    In most case, ICSP is the AVR,an Arduino micro-program header consisting of MOSI, MISO, SCK, RESET, VCC, and GND. Connected to ATMEGA 16U2-MU. When connecting to PC, program the firmware to ATMEGA 16U2-MU.

    KS0001 5-9.pngRESET Button

    You can reset your Arduino board, for example, start the program from the initial status. You can use the RESET button.

    KS0001 5-10.pngD13 LED

    There is a built-in LED driven by digital pin 13. When the pin is HIGH value, the LED is on, when the pin is LOW, it's off.

    KS0001 5-11.pngUSB Connection

    Arduino board can be powered via USB connector. All you needed to do is connecting the USB port to PC using a USB cable.

    KS0001 5-12.pngATMEGA 16U2-MU

    USB to serial chip, can convert the USB signal into serial port signal.

    KS0001 5-13.pngTX LED

    Onboard you can find the label: TX (transmit) When Arduino board communicates via serial port, send the message, TX led flashes.

    KS0001 5-14.pngRX LED

    Onboard you can find the label: RX(receive ) When Arduino board communicates via serial port, receive the message, RX led flashes.

    KS0001 5-15.pngCrystal Oscillator

    Helping Arduino deal with time problems. How does Arduino calculate time? by using a crystal oscillator.
    The number printed on the top of the Arduino crystal is 16.000H9H. It tells us that the frequency is 16,000,000 Hertz or 16MHz.

    KS0001 5-16.pngVoltage Regulator

    To control the voltage provided to the Arduino board, as well as to stabilize the DC voltage used by the processor and other components.
    Convert an external input DC7-12V voltage into DC 5V, then switch DC 5V to the processor and other components.

    KS0001 5-17.pngDC Power Jack

    Arduino board can be supplied with an external power DC7-12V from the DC power jack.

    KS0001 5-18.pngIOREF

    Used to configure the operating voltage of microcontrollers. Use it less.

    KS0001 5-19.pngRESET Header

    Connect an external button to reset the board. The function is the same as reset button (labeled 9)

    KS0001 5-20.pngPower Pin 3V3

    A 3.3 volt supply generated by the on-board regulator. Maximum current draw is 50 mA.

    KS0001 5-21.pngPower Pin 5V

    Provides 5V output voltage

    KS0001 5-22.pngVin

    You can supply an external power input DC7-12V through this pin to Arduino board.

    KS0001 5-23.pngAnalog Pins

    Arduino UNO board has 6 analog inputs, labeled A0 through A5. 
    These pins can read the signal from analog sensors (such as humidity sensor or temperature sensor), and convert it into the digital value that can read by microcontrollers) Can also used as digital pins, A0=D14, A1=D15, A2=D16, A3=D17, A4=D18, A5=D19.

    KS0001 5-24.pngMicrocontroller

    Each Arduino board has its own microcontroller. You can regard it as the brain of your board.
