UBLOX M8 I2C pull-up considerations

0 votes

I read in the M8 modules hardware integration guide, that the ddc/i2c pins have internal pull-up resitors but I am not able to find the specific values of these resistors. Do these resistors allow for max speed bus functionality?

I need to know these values, in case an i2c master on a nother pcb is already providing pull-ups!

kind regards,

A quick measure of current into an external load R indicates equivalent of a 10K to 15K internal pull-up.
