    keyestudio UNO with pin headers has the same basic functions as keyestudio UNO R3 BOARD. It is a microcontroller board based on the ATMEGA328P-AU, which has the same function as ATMEGA328P(-PU), 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 crystal oscillator, a USB connection, a power jack, 2 ICSP headers, and a reset button. 
    This UNO with pin headers makes the improvement based on keyestudio UNO R3 board.
    It breaks out all the digital and analog pins in the form of 3PIN headers (G, V, S). 
    S pins correspond to all 14 digital pins, 6 analog pins. G pins for ground. V pins for VCC. You can control the voltage of VCC via a slide switch for 5V or 3.3V. 
    When switched to 5V, level on serial communication port is 5V, voltage of pins is 5V. When switched to 3.3V, level on serial communication port is 3.3V, voltage of pins is 3.3V.
    It also breaks out two 4PIN headers for serial communication and IIC communication. So it is more easier to connect external sensors and modules. 
    As for keyestudio UNO R3 board, its voltage-regulator chip is NSP1117. When connect external power, output 5V, drive current is 1A.
    But for this keyestudio UNO with headers, its voltage-regulator chip is MP2307DN. When connect external power, output 5V, drive current is 2A.
    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.

    Element and Pin Interfaces

    Here is an explanation chart of what every element and interface of the board does: 
    UNO 引脚标图2.jpg

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

    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-AU.

    KS0001 5-2.pngSerial Communication Pin

    Connect to serial communication. 4Pins (GND, VCC (3.3V or 5V controlled by slide switch), RX, TX)

    KS0001 5-3.pngGround

    Ground pins

    KS0001 5-4.pngV Pins (VCC)

    Power the external sensors and modules. Select the voltage of 3.3V or 5V via a slide switch.

    KS0001 5-5.pngDigital I/O

    It has 14 digital input/output pins, labeled D0 to D13 (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 D3, D5, D6, D9, D10, and D11 can be used to generate PWM. 
    For digital port, you can connect through female headers, or through pin headers (labeled S) of 2.54mm pitch.

    KS0001 5-6.pngAREF

    For Analog reference. Sometimes used to set an external reference voltage (0-5V) as the upper limit of analog input pins.

    KS0001 5-7.pngSDA

    IIC communication pin

    KS0001 5-8.pngSCL

    IIC communication pin

    KS0001 5-9.pngICSP (In-Circuit Serial Programming) Header

    ICSP is an 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 5-10.pngMicrocontroller

    Each control board has its own microcontroller. You can regard it as the brain of your board.
    Microcontrollers are usually from ATMEL. Before you load a new program on the Arduino IDE, you must know what IC is on your board. This information can be checked at the top of IC.
    The microcontroller used in this board is ATMEGA328P-AU.

    KS0001 5-11.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 5-12.pngTX LED

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

    KS0001 5-13.pngRX LED

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

    KS0001 5-14.pngPower LED

    LED on means that your circuit board is correctly powered on. Otherwise LED is off.
