Is it possible to use the white I2C plug on the kc868-ap board. If yes to what gpio numbers are the pins connected? 
I would like to use this to connect pushbuttons via a IC bus interface as remotely I do not have enough wires to connect all the wall pushbuttons directly to the inputs of thet board.  I use  esphome
IIC SDA:GPIO4
IIC SCL:GPIO16
