VCC_IN (DC 3.3V@ 5% power Input)
This is the DC power supply input pin for GPS system. It provides voltage to module.
The power supply must add bypass capacitor (10uF and 1uF). It can reduce the Noise
from power supply and increase power stability.
If shutdown the REB-1315S5 module, please remove the VCC_IN Pin voltage into
Hibernate mode.(It’s will keep the Warm start and Hot start function work well)
