    This is a breakout board for the PCA9306 dual bi-directional voltage level translator. You can use this board allow devices of different voltages to communicate.
    The PCA9306 is a dual bi-directional I2C and SMBus voltage level translator that's operational on the low side from 1.0V to 3.6V and on the high side from 1.8V to 5.5V. Simply apply your low- and high-side reference voltages to the
    VREF1
    and
    VREF2
    respectively, connect your I/O, and drive the
    Enable
    pin High to open bi-directional voltage translation without needing to use a direction pin.
    Hookup Example
    The breakout board has seven pins that need to be connected to function properly.
    VREF1
    ,
    SCL1
    , and
    SDA1
    all connect to your lower-voltage part.
    VREF2
    ,
    SCL2
    , and
    SDA2
    connect to your higher-voltage part. The
    GND
    pin needs to be connected to Ground in your system. The final through-hole on the board, labeled
    NC
    , does not need to be connected to anything.
    To connect the board, solder headers into the through-holes, and use jumper wires between devices, or solder wire directly to all your boards.
    The following example connects an
    Arduino Pro Mini 5V
    to an
    HMC5883L Magnetometer Breakout Board
    which runs at 3.3V and communicates over I2C.
    Click on the image or use the

    feature of your browser to see it full size.
    That image shows the HMC5883L running from a 3V supply via two AA batteries, and the Pro Mini running from a 5V barrel jack input. These are merely examples; you can supply each component's power however you like. The important thing is that both the lower voltage and higher voltage must be supplied.
    The connections made to/from the PCA9306 Voltage Translator Board in that example are as follows:
    HMC5883L
    ⇔
    PCA9306
    ⇔
    Pro Mini 5V
    3.3V
    ↔
    VREF1
    VREF2
    ↔
    5V
    SCL
    ↔
    SCL1
    SCL2
    ↔
    A5
    SDA
    ↔
    SDA1
    SDA2
    ↔
    A4
    GND
    ↔
    GND
    NC
    All you need to do is make those connections. You don't need to use any special code with the PCA9306 board.
