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 of
RS232 and Micro-USB cable are necessary, if you want to use UART in order to output NEMA. So the
easy way is that use Micro-USB cable which both provides the power and output NEMA. You can make
alternation between UART port and Micro-USB interface via switch (S401).
