where to get IIC pin #10

Closed gfilippi closed 1 year ago

I would like to connect an external I2C device but it is not clear to me where we can get the same IIC_SDA IIC_SCLK that is used for the PMU. Which pin should we use for electrical connection to the system I2C bus?

PMU SDA SCL is not led out. Please use another IO port as the interface of the IIC device. You can use IO2 (SDA) and IO1 (SCL) as the access of external IIC devices. By default, pull-up resistor has been added to these two IOs
