3.1. USB Interface
Figure 4: Micro-USB Interface
The main power is supplied via Micro-USB interface. Quectel provides two ways for data communication:
Micro-USB and UART interface which are controlled by serial port alternation switch (S401). Both RS232
and Micro-USB cable are necessary, if you want to use UART to output NEMA. So the easy way is that
use Micro-USB cable which provides both the power and output NEMA. You can make alternation
between UART port and Micro-USB interface via switch (S401).
