PowerC I2C and power switch



  • Re: PowerC
    Just got one of these to use with an I2C device needing more power. PowerC hat came with the power switch broken in pieces. Did not realize the hat blocks access to the 8 pin header. Anyone know the pinout on the 4 pin connector marked Port A which I understand is an I2C output, no datasheet found ? Anyone have one that has a working power switch or workaround?



  • There are quite a few pin outs for pin A as its a groove i2c port.
    From power button side
    White - SCl
    Yellow - SDA
    Red - 5V
    Black - GND

    Please note that there are some cables with the white and yellow wires switched.
