Connecting to a Host

After initial operation of the monitor with the BQStudio software, consider operating the board connected to and controlled by a microcontroller board. To do this, unpopulate J6 and J2, and populate J1 and J5. J6 and J2 disconnect the I2C lines of the BQ76905 from the on-board MCU. J1 and J5 connect the I2C pullup resistors to REGOUT.
