Project 8：Lithium Battery Power Module
(1)Project Introduction
This module integrates a charging and discharging chip, which can be
interfaced with an external rechargeable battery through the PH2.0MM
interface. In the experiment,we use a single lithium battery.
It has a Micro USB port and a charging port for solar panels, which can
supply power for an external lithium battery.
In addition, this module has a boost module which can increase the
voltage of batteries to 6.6V. The DIP switch on the module is the OUTPUT
switch of 6.6V. The pin G and V can output 6.6V and the pin S can read the
battery voltage after the resistance 1/2 voltage
