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). If you want to
use UART in order to output NEMA, both RS232 and Micro-USB cable are necessary. So the easier way
is to 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).
