3 Power Supply

L710HG development board provides two methods for power supply: External DC 5 V adapter and 3.8 V

DC power supply directly. Through an external DC 5 V adapter power supply, the power supply voltage

regulator on the development board piece of power supply will be converted to about 3.8 V, power supply

for the module. These two modes can be switched by S1. Switch S1 to the top when using DC 5V

adapter and Switch S1 to the bottom when using battery power. The power indicator (LED1 next

to the power switch) will light up when the system is powered on.

As shown in the figure below:
