USB Interface l e t l c a e i t u n Q ide f n o C 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). L86_EVB_User_Guide Confidential / Released 10 / 20 GNSS Module Series L86 EVB User Guide 3.2.
