Fuel Gauge (optional)
The module can optionally support an external Fuel Gauge solution.
In this case, an external IC that is capable of measuring the current flow in and out of the
module must be added on the carrier board.
Figure 23 shows an example of a typical connectivity of such an external fuel gauge to the
module.
Detailed design - TBD
