Connecting to a Host

After initial operation of the monitor with the BQStudio software, it may be desirable to operate the board connected to and controlled by a microcontroller board. To do this, depopulate J6 and J2, and populate J1 and J5. J6 and J2 disconnect the I2C lines of the BQ76907 from the on-board MCU. J1 and J5 connect the I2C pullup resistors to REGOUT.
