 For I<sup>2</sup>C communication, please be sure to remove all additional pull-ups on the I<sup>2</sup>C bus. u-blox modules include internal pull-ups on the I<sup>2</sup>C lines (sometimes called DDC in their manuals). Cut all I<sup>2</sup>C pull-up jumpers and/or remove them from peripheral boards. Otherwise, various data glitches can occur. See issues [38](https://github.com/sparkfun/SparkFun_Ublox_Arduino_Library/issues/38) and [40](https://github.com/sparkfun/SparkFun_Ublox_Arduino_Library/issues/40) for more information. We recommend running the I<sup>2</sup>C bus at 100kHz.
