Quectel Smart EVB G5 - UART Interfaces

Smart Module Series
Smart_EVB_G5_User_Guide 49 / 66
The reference circuit and pin assignment of J1002 are the same as J1001’s.
UART Interfaces
Smart EVB G5 provides two UART interfaces: main UART and debug UART. The main UART interface
can be used for data transmission and AT command communication. The debug UART interface is used
for debugging.
