I need to connect a sensor to CubeCell board via I2C bus. Based on the schematics, I believe the onboard SH1107 OLED communicate with the MCU via I2C_SDA and I2C_SCL pins (#40 & #39).
Therefore, I cannot use these two pins to connect to the sensors.
There is a 2nd set of I2C pins (#37 GP9 & #36 GP8) based on the pin diagram
My question: what is the I2C address of the 1st and 2nd set of I2C bus?
