    Introduction for Digital pins

    • RX:D0
    • TX:D1
    • SPI interface SS:D4
    • SPI interface MOSI:D11
    • SPI interface MISO:D12
    • SPI interface SCK:D13

    LED: there is an onboard LED, please connect the LED to Digital pin 13 (D13).

    D&A: new version IO expansion shield printed with "D" and "A".

    "D": Represents a digital signal. That is, connect to the digital pins of mainboard.
    "A": Represents an analog signal. That is, connect to the analog pins of mainboard.

    Compared with limited power-supply interfaces in mainly mainboards, IO Expansion Shield increase a large amount of power-supply interfaces and GND pins. Therefore, users no need to worry about the shortage of power supply interfaces when connecting many modules.

    Special description of the color distinction in DF:

    Color Function
    Green Digital Signal
    Blue Analog Signal
    Red VCC(+)
    Black GND(-)

    FAQ

    • PWR_IN & SERVO_PWR

      1.The power supply of the digital pin is connected to SERVO_PWR, and SERVO_PWR supplies 5~12V. After the servo power input interface is powered, it can only power the D0 to D13 digital pin, but not the board. If the program burned in the board needs to run, the board must be connected to the other power supply. PWR_IN is connected to vin, PWR_IN power supply 6~12V. The power supply of the I2C interface on the Shield is 5V. Use the 5V/3.3V jumper caps to select the power supply for the digital and analog pins.
