How To Use

The 3.3V to 5V I2C Hub Board is easy to use. Typically, one I2C bus will be connected to 5V and the other to 3.3V. The main connector to the computer will typically have 3.3V in the case of a Raspberry Pi) or 5V (in the case of most Arduinos or the Pi2Grover Interface Board). The other side of the bus (with all the I2C devices on it), typically is unpowered and you will either need to hook up 3.3V or 5V depending on what your computer is.

The Grove 3.3V to 5V I2C board has a bidirectional level translation circuit between the SDA and SCL lines. Ground is common between both sides of the board. The Grove power line is NOT connected between the 3.3V and the 5V sides of the board. Which ever side is not powered but the attached computer must be connected to the power.
