    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.
