 If you are using the Dead Reckoning Sensor Fusion or High Dynamic Rate messages, you will need to make more small changes to your code. Please see the [dead reckoning examples](./examples/Dead_Reckoning) for more details. There is more detail available in [Theory.md](./Theory.md#migrating-your-code-to-v20) if you need it.
 
-## Max (400kHz) I2C Support
+## Max (400kHz) I<sup>2</sup>C Support
 
 To achieve 400kHz I2C speed please be sure to remove all pull-ups on the I2C bus. Most, if not all, u-blox modules include internal pull ups on the I2C lines (sometimes called DDC in their manuals). Cut all I2C 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. If possible, run the I2C bus at 100kHz.
