<![CDATA[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?

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.
